Poking at #AdventOfCode in #uiua again today, trying to remember some of the language from a year ago. Here's Day 2:

⊜(□⊜⋕≠@ .)≠@\n.

SafeA ← +⊃(/×∊⇡¯3|/×∊+1⇡3)⧈(/-)2

SafeB ← >0/+≡(SafeA▽) ⊙¤ ⊞≠.⇡⧻ .

∩(/+) ∵⊃(SafeB°□|SafeA°□)

@xvw I think it's easier to grok than APL or J, and the docs and interactive pad are great for learning stuff. Worth a dabble if it tickles your brain!

@sanityinc @xvw J is like catnip for me. Evil catnip. I've been curious about uiua vs bqn as far as the next-gen APLs go though 🤔 (edit: oh, uiua is stack-based too probably shouldn't have called it a next gen apl then)

@dfarmer @xvw the stack parts fit really nicely with the array bits IMO

@xvw Okay, some review feedback:

• Looks pretty solid to me overall

• You can remove the empty ocaml-eglot-{req,util} custom groups to avoid clutter

• (add-hook 'find-file-hook #'ocaml-eglot--file-hook) — this means you modify the global find-file-hook every time the minor mode is toggled on or off in any buffer (ocaml-eglot.el:367). This minor mode should get enabled in the new .mli file buffer, so perhaps just call ocaml-eglot--file-hook directly?
