Yea I’ve wanted to try using logict to do some larger logic programming stuff. I’ve done it with list monad but found a lot of speed issues, never quite figured out why it was so slow.

Well, lists are really slow.
To be more precise: lists in your code can be really fast, if the compiler can find a way to never actually have lists in the binary it produces. If it actually has to have lists at runtime, it's generally not all that fast.
Yeah I figured that, but the combinations I was dealing with really weren’t that many.
The problem was https://xmonader.github.io/prolog/2018/12/21/solving-murder-... and trying to solve it with list monad. Someday I hope to get back to it.
