I didnt even know than Haskell has this operator. " . " breaks my brain when i read

Should be fixed in TS.

in ts same problem..

I'm so confused.

What on Earth
Nice one.

Wait, wha- 🤯

that shocking me

It definitely happens in ruby (too): see this or this...

cool

I don't doubt you are correct, but I did this more than a few braincells ago and can no longer read the description or my solution.

I'd suggest suggesting a new fixed test to the kata author ( because this might happen in other languages as well ).

This should fail, it will incorrectly judge the string "abbb"

Your list comprehension can be replaced by replicateM 4 perms

Works, thanks!

I updated the generation of the random string. Hopefully this shouldn't happen anymore.

This line:

[ '(1|((1&(0^1))&(0&0)))' ]

is in your list 3 times, there are probably more duplicates.
