I really enjoyed learning Prolog in university, but it is a weird language. I think that 98% of tasks I would not want to use Prolog for, but for that remaining 2% of tasks it's extremely well suited for. I have always wished that I could easily call Prolog easily from other languages when it suited the use case, however good luck getting most companies to allow writing some code in Prolog.

That is where Lisp or Scheme weirdly shines. It is incredibly easy to add prolog to a Lisp or a Scheme. It’s almost as if it comes out naturally if you just go down the rabbit hole.

“The little prover” is a fantastic book for that. The whole series is.

I worked through the little scheme but not the little prover, I think Ill take a look at that. Thanks.

One can of course add the same stuff to other languages in form of libraries and stuff, but lisp/scheme make it incredibly easy to make it look like part of the language itself and make seem a mere extension of the language. So you can have both worlds if you want to. Lisp/scheme is not dead.

In fact, in recent years people have started contributing again and are rediscovering the merits.
