It is AOC time again, so i try to pick up my 2023 codebase and start again. But quite a few changes happened to the language. Where do i find how to move away from Nat
? And what happened to Str.graphemes?
Str.grapheme was removed here, which has some good guidance: https://github.com/roc-lang/roc/pull/6395
And as for Nat: https://github.com/roc-lang/roc/pull/6422
Luke has updated his 2023 solutions so those may be helpful as well
