I implemented a ring buffer and it works.

I never used capacity on something else but I implemented a capacity()
function. The memory I allocated is accessed through a span, which
doesn't have a capacity.

Sorry, the code is from a different post I copied and tested, forgot which post.

#include <iostream>
#include <random>
#include <algorithm>
#include <map>
#include <climits>

using namespace std;

int main(int argc, char** argv)
{
        mt19937_64 mt;
        uniform_int_distribution<int> uid( INT_MAX, INT_MAX );
        vector<int> vi;
        vi.reserve( 1'000 );
        for( size_t i = vi.capacity(); i--; )
                vi.emplace_back(uid( mt ));

The implement of ring_deque looked like a deque, not a "ring buffer".

Ring buffer is fixed sized (e.g. N). In short, you can keep pushing data into it, 
the ring buffer can only keep the last N elements.

Internally it's a ring-buffer with a sliding window.

It looks like infinite loop. 
Didn't you mean either
	for(size_t i=arr.capacity() ; i>0; --i)
or 
	for(ptrdiff_t i=ptrdiff_t(arr.capacity())-1; i>=0; --i)
?

There's no such loop in my code. I'm not using capacity on any
foreign object but I implement capacity-functions myself. And
I rarely use an integer-index to iterate over a linear container
but I use iterators because this is sometimes faster.

Value polymorphism requires the value to be in the function prototype, not
buried in some code underneath. Like all polymorphism its just a syntatic
and semantic nicety as it can simply be done using if-then style code.

Calling a function<>-object is always value polymorphism.

There's no conditional jump inside a function<>-object to decide which
function actually to call. And when you use function<>-objects you need
loose coupelng and then ifs are no alternative.

Neither "value polymorphism" nor "polymorphism by value" is a
common term.

They mean different things.

Polymorphism by value was discussed in a 1993 paper by Xavier
Leroy.

Value polymorphism, as it is described in the cited web page, is
simply overloading of variables rather than functions.
(Overloading is often called "ad hoc polymorphism".)

Neither overloading of functions nor overloading of variables has
anything to do with functional programming.  Overloading might be
supported in some functional programming languages (and it is in
some non-functional languages, notably C++), but overloading is
orthogonal to the notion of functional programming.

Supporting polymorphism is not a pre-requisite either for doing
functional programming or for a language being a functional
language.  There are plenty of functional programming languages
that don't have facilities for polymorphism, as for example the
original Lisp.

Because not many languages support it.

Not in the version of english I speak they don't.

Thats his opinion.

Without it many of the standard examples of functional programming simply
won't run.

Since when was Lisp a functional language? Scheme maybe.

Are you talking about what is more commonly referred to as pattern matching?

	factorial 0 = 1
	factorial n = n * factorial (n - 1)


That is not what is generally meant by polymorphism, it's just an 
alternative (but often very neat) way to write a conditional :

	factorial n = if n < 2
			then 1
			else n * factorial (n - 1)

I've already posted a link to an article about it. Whatever you want to call
it, the polymorphic function called is based on the value passed to it, not
the type.

That applies to all types of polymorphism. All decisional code however its
written eventually ends up as some kind of assembler cmp/jmp combination.
Might be 2 opcodes, might be 1, doesn't matter, same thing.

The key point of polymorphism - as I see it - is that the source code 
doing the dispatching does not know the details of the possible matches 
or targets.  Thus C++ virtual methods support polymorphism - a function 
call call "p->foo()" for "p" of type "T*" without knowing anything about 
how many descendent types of "T" exist or how they different.  All it 
needs to know is that the base class "T" has a virtual method "foo".

This cannot be done with a series of cmp/jmp instructions - it ends up 
as an indirect call instruction.


For static or compile-time polymorphism, the details of the generated 
code are not as important, but you still want the code that uses the 
polymorphic types, values, objects, whatever, to be independent of the 
things themselves.  You get that in C++ CRTP templates, for example.


I don't claim to have any kind of "official" definition of the term, but 
I am pretty confident that what you seem to be talking about (AFAIUI) is 
not something many people would refer to as "polymorphism"

Not sure how that differs with value polymorphism.

It could quite easily, but yes, a call is more likely. Point still stands
however.

When you say "people" you seem to be talking about people in the C++ world
or perhaps C-type language world. Polymorphism is more than just type and 
virtual functions.

I explained that - look at my answer below for another attempt.

No, it could not be done - thus your point does /not/ stand.

Suppose you have these files :

// foo.h
struct Foo {
	virtual void doFoo();
};

// foo.cpp
#include <stdio.h>
#include "foo.h"

void Foo::doFoo() {
	printf("I'm a Foo, and I'm doing foo\n");
}


// bar.h
extern void doLotsOfFoo(Foo * pf);

// bar.cpp
#include "foo.h"
void doLotsOfFoo(Foo * pf)
{
	for (int i = 0; i < 10; i++) {
		pf->doFoo();
	}
}

// foobar.cpp
#include <stdio.h>
#include "foo.h"
#include "bar.h"

struct FooBar : Foo {
	void doFoo();
};

void FooBar::doFoo() {
	printf("I'm a FooBar, and I'm doing foo\n");
}

void testFoo() {
     FooBar fb;

     doLotsOfFoo(&fb);
}


That's run-time polymorphism using class inheritance and virtual 
functions.  When compiling doLotsOfFoo(), there is no way for the 
compiler to know what types it might be called with - there is no way it 
could be compiled as a selection of comparisons.  Baring full-program 
optimisation, indirect calls are the only way to handle it.

I realise the term is used in other languages too (although the emphasis 
here is of course on C++, since we are in c.l.c++).  But no, I am not 
restricting "people" to C++ programmers - they may be programmers of any 
languages, including functional programming languages.

No you didn't because like Bonita you have no idea what value polymorphism is.

Really? What exactly do you think an assembler call instruction is other
than a single opcode stack push and jump?

And you don't think indirect jump instructions exist?

We can add assembler to the list of things you don't understand.

The term "polymorphism" is used in reference to /types/, not /values/. 
I am not new to programming, and have used a large variety of languages 
(including functional programming languages), but have not heard the 
phrase "value polymorphism" before.  So I am trying to get /you/ to say 
what /you/ mean by it.  Maybe it's just a name you and a few other 
people use for pattern matching.

Yes, that's what a call instruction sequence is on many (but certainly 
not all) processors.  But that's not what you wrote.  You wrote that 
"all types of polymorphism" are just conditionals that boil down to 
"cmp/jmp" instructions.

Maybe you misread, or expressed yourself badly, or mixed up what you 
were trying to say.

A call is, fundamentally, just a jump with a returned address stored in 
some way.  I'm not making a distinction between indirect calls and 
indirect jumps, as that's just detail.
