Not praying to the god of lambda calculus [π beats α] (Was: Introduction to AI Accelerator Prolog [π-WAM of Dogelog])

Show all headers | View raw

Hi,

Somebody tasked the logic programming community
to make an α-Prolog, i.e. have some alpha
conversion whatever builtin, plus maybe nominal
logic fresh variables whatever.

But who reads such nonsense in 2026:

Lifting E-Graphs: A Function Isn't a Constant
https://arxiv.org/abs/2606.22734

So you see where I am aiming with π-WAM, surely
not α-Prolog . I wouldn't care less about  α-Prolog.
π is more fun than α, and working on WAM is more
fun then creating some silly prototype of a

REPL of a homunkulus of a Prolog. π beats α:

- α = abstract, academic, awkward
- π = parallelism, performance, practical

Bye
