In halls of Cambridge, where catnip sways,
Sat pioneers lost in existential haze.
“Here lies a term!” they cried, “both bound and free,
A bag of possibilities, as far as we see.”

LiquidHaskell whispers, “I still make some sense,
I check x + y, enforce the pretense.
But only 1% — the rest, pure ado,
Existentials and predicates, I haven’t a clue.”

Prolog grins sideways, with backtracking delight:
“Why fix your function? Let each path take flight!
X and Y and Z — all three may roam,
I’ll find a solution, or many, for home.”

Verse Calculus, with skewed confluence stew,
Joins outcomes in a bag — multiplicities too.
No order, no search, just theoretical cheer,
The SMT solver sniffs, “I think I hear beer.”

Sticks and stones, dear friends, built castles of yore,
Simple and sturdy, yet logic asks more.
Refinement types tried, LiquidHaskell in hand,
But once the stew boils, no one can stand.

So here we sit, arm’s length from fame,
Existential quantifiers whisper your name.
A mockery? Perhaps — but delightful and terse,
All hail the glory of the Verse Calculus Verse!

Hi,

Thats why open source slowly becomes a failure.
Because it is full of nickname shape shifters,
that hide behind anonymity. SWI-Prolog is no

exception. A bunch of anonymous crack heads.
Its not some Script Kiddies. They are basically
mafia hackers. And if you have some high CPU

process that doesn't automatically go away,
you possibly got a backdoor via an opensource project.
Sovereign Tech Fund (STF) will not help, since

they will shy away from loosing their anonymity.
And after all the mafia hackers are also well
endowed, have their own funding.

Hi,

Ok the idea is trivial. Vibecoding is pair
programming, with an AI counterpart. But what
is Vibesniffing? Ok, now we finally hit the

critique expert system domain. First study this:

Mondrian Code Review On The Web
Google Tech Talks - Guido van Rossum
November 30, 2006
https://www.youtube.com/watch?v=sMql3Di4Kgc

Vibesniffing would be with an AI counterpart. Like
AI Gerrit etc.. Doesn’t look like LiquidHaskell
has made it an imprint here? ChatGPT thinks since

LiquidHaskell is not made for "how code feels".
I strongly oppose to this view. Code review
could be inherently fuzzy, since most

software evolves through:

- Imperfect requirements
- Imperfect code
- Iterative refinement
- Etc.. etc..

#640616 — From Feferman to Peyton Jones, no luck with ∃ (Re: 2025 Obituary: Skew Confluence (aka “Stews” 😆))

Hi,

Now this is an interesting find. It seems
not only the Verse Calculus by Peyton Jones
hit a wall with existential quantifier ∃.

Especially the type free case. Its like in
Rossy Boys Russell thing, people are not
anymore trained to think about "individuals",

the are more bothered by "bags", because this
is what the Antinomies of the formal revolution
tought us. But the formal revolution has also

some nice easter eggs, like Fefermans OST
("Operational Set Theory"), an early form of
Predicte Abstraction. With each formula A is

associated a term t_A such that:

     ∀x[A(x) <=> t_A(x) = tt]

https://math.stanford.edu/~feferman/papers/OperationalST-I.pdf

The nice thing about the t_A, its a term,
possibly a open or closed term, depending
on whether there are parameters, and thats

what I am now doing for Arrow Functions, when
the Prolog systems compiles 0rReference(P1,..,Pk),
its basically a term, an individual, that

later gets called by call/n, which makes the
translation for individual to proposition.

Bye

P.S.: But somehow Feferman shyed away from
definition the unbounded existential quantifier
as a projection, there is a easy geometric

intution, and every SQL database can do it.
Instead he falls back to some Hilber Epsilon
analogue such as:

Given A(x) = ∃yB(x, y) and t_B for B(x, y);
then we can take t_A = λx.t_Bx(C(λyt_Bxy)),
using the general choice operator C.

https://math.stanford.edu/~feferman/papers/OperationalST-I.pdf

Funny!

Hi,

Lets say we have an ost term t_A for
some sets of pairs such that:

   t_A(x,y) = tt <=> A(x,y)

Question is what is the term t_B for:

   B(x) <=> ∃y A(x,y)

In the Arrow Functions to Horn Clause
translation. The existential quantifier
is a feature of the Clark Completion.

In terms of Cabezas notion:

   t_B = { ''(x) :- t_a(x,y) }

Bye

P.S.: Why does it remind me of the
K Combinator? Well we have:

∃y t_B(K(x,y)) = ∃y t_A(x,y)

Not sure whether this is useful.
Although the above is true because the
combinator K is defined as Kxy = x,

it can be quite misleading, since
this here does not necessarely hold:

/* Not necessarely */
{ y | t_B(K(x,y)) } = { y | t_A(x,y) }

So if Feferman had the empty set, he could
also check for inhabitation, and bootstrap
existential quantifier via parameterized bags:

t_B(x) = ( { y | t_A(x,y) } =/= {} )

But we don't like bags here..

#640631 — Not Ross Finlayson: Pioneers Cliff B. Jones (Was: 😂 "Plog-like" - that should be the official term!)

Hi,

Since LiquidHaskell, VerseCalculus, etc.. have
the tasted of reinventing the wheel, and still
gloriously failing, I will start a series of

Pioneers of Program Formalization, and begin
with Cliff B. Jones (born 1 June 1944) is a British
computer scientist. This piece looks a little

archaic, but is full of funny examples:

4.1.2 Examples
Basic statements:
a := p+q
goto Naples
START:CONTINUE:W := 7.993

A formal Definition of Algol 60
August 1972 - Cliff B. Jones et al.
http://homepages.cs.ncl.ac.uk/cliff.jones/publications/Other-TRs/TR12.105.pdf

This post is especially a donation to Ross Finlayson,
who still is seeking consistent foundationalism,
as if Russell had written the Letter to Frege,

just yesterday, while a computer program might
simply goto Naples.

Bye
