I used Claude that created a terminal based table viewer from rust first, to lean , and finally to Haskell. https://github.com/co-dh/tv-hask/tree/main

I give up rust because it’s not functional enough. There aren’t many things Claude can prove about a table viewer, and Haskell fits very well, and have enough libraries. Claude is pretty good at Haskell. I barely write Haskell before but I do know monad.
