Hi,

Woa! Thats a very sad and non fitting statement:

"This was before I was indoctrinated into
ISO Prolog and the ways of monotonic logic
programming. Shen Prolog has many semantic
and syntactic limitations that Scryer Prolog
does not. Also, I now know constraints are a
much better, purer solution to the problems
mode declarations were meant to address"
https://github.com/mthom/scryer-prolog/issues/3410#issuecomment-5030471183

Ok, here is the summer challenge, thats the easy one:

     SQL --> Prolog --> WAN

Here come two variations, slightly mindboggling maybe?

     SQL --> AST --> VDBE

     SQL --> Prolog+Modes --> π-WAM

Bye

BTW: What is VDBE? Some abstract machine, that can
be used to run SQL, following some ideas here:

Database Co-Design With Asynchronous I/O
https://penberg.org/papers/penberg-edgesys24.pdf

Or to run Doom:

Doom on the Turso VDBE
https://github.com/tursodatabase/turso-vdbe-doom-example

What if we would run Doom with π-WAM, on a GPU,
using multiple shaders. We could add some ray tracing.
