But it does interfere with native behaviour ( for .. in ). Non-enumerability should be specified and tested.

I have fixed the Haskell translation to generate inputs 0 .. 100_000, instead of 1200 a hundred times (perimeter 1200 * x is (perimeter 1200) * x, not perimeter (1200 * x)). Also added explicit import and export lists where applicable, and moved showing inputs to failure messages.

ETA: Some solutions have been invalidated because of insufficient performance. 100_000 may be higher than you intended.

marking issue as resolved, as both katas you refer as duplicates are retired now. If there are any other duplicates, please raise a new issue.
