I don't know of a way, but this works. It's all part of the same thread.

Is it weak typing to overload a function?
//C++ likes this a lot.
int foo(int x,int y) {return x*3+y;}
double foo(double x,double y) {return x*3+y;}
This is definitely making the term "strongly typed language" fairly useless.

+1. My expectations are:
1) The Boolean value "True" might be the same as a nonzero integer, or
might not; it would make sense to use inequality comparisons with
zero, MAYBE, but not with 1. So I don't particularly care what the
language does with "1 < True", because it's not something that I would
normally do.
2) "1"+1, in any high level language with an actual string type, I
would expect to produce "11". It makes the most sense this way; having
it return 2 means there's a special case where the string happens to
look like a number - meaning that " 1"+1 is different from "1"+1. That
just feels wrong to me... but I'm fully aware that many other people
will disagree.
Yep, it's pretty subjective.

Point. I stand corrected. I tend to think of a char* as "being" the
string, even though technically it only points to the beginning of it;
it's the nearest thing C has to a string type. (To be honest, it's
still a lot better than many high level languages' string types for
certain common operations - eg trimming leading whitespace is pretty
efficient on a PSZ.) In your example, p would be some integer value
that is the pointer, but *p is 5. However, there's really no syntax in
C to say what the "string value" is.
