What a beautiful way to use list monad

Where is reverse in my code?

Also working submission test cases

Make it so that features show sorted by upvote value

Maybe he has skipped some katas and wants to redo them.
It would should be simple to get implemented so why not?

Maybe allow like lvl 2 tags which are not used for searching and filtering katas when looking for a challenge but to put tags which point out some special characteristics of your kata so when someone else is making a kata he first checks out if someone else has made a kata with those characteristics

WHAT SORCERY IS THIS???????????????

heres an SS http://i.imgur.com/0t8x5Ya.png

It says my solution fails at ["a","A"]
If its case insensitive shouldnt there then be no wrong answer?

There seem to be issues with the test cases

It seems to me that when I try to submit I get an error that the problem was at the line which is not in my source. Seems like my solution get evaluated along with some other ones.

I wouldn't mix idiomatic with something that was used as an implementation standard. The fact that it's short and does the job does not mean it is readable when making a quick code review. I suppose I'll refrain from taking a strong stance untill I'm actually good at haskell

Isn't this more code golf than best practice?
I'm new so it might be it but it doesn't seem too obvious whats happening
