Done

Approved

Random tests available here

You are introducing an Eq a constraint with your use of elem. Don't use elem ( or elemIndex ). find and findIndex do not introduce such a constraint.

The given signature is [[a]] -> [a]. You can't just go around adding constraints to given signatures; you're not implementing the spec.

No random tests.

Thanks! Glad you enjoyed it.

Great kata! Forced me to really get comfortable with ReadP ;)

Cool. Can you approve it?

Thanks, this is definitely an improvement.

Added (truly) random tests, with 0 and 5 clues included.

Thank you :)

I've been away from Codewars from a while, but better late than never -- thanks for your kind words!

I wonder if you're aware of the issue that Blind4Basics has raised for this kata?

rank suggestions need to be cleaned up before approval.

I'm not sure what it's about -- perhaps not everyone has given a suggested rank for this kata. Anyway, I thought that you might like to look into it if you want to get the kata out of beta.
