This was a pain - a beautiful, sensational type of pain.
THANK YOU!

fair

The comment was from before you changed it.
Still, no real solution would use more tgan one line, it's an unnecessary check that clutters the kata title.

but semicolons and newlines aren't allowed (i forgot to add that test)

I agree, just call it "Code Golf: ..." instead. This is consistent with other code golf kata's.

i forgot i removed that test...

eh maybe; i'll just up it to like 40

I'm not sure about the new character limit. Seems a bit too strict. Depends how much variations you would like to see pass this kata.

you'd have to be very lucky

done

great, I learned something today

r"" means raw string (just means that you do not have access to any escape characters and you do not need to escape \), not regex

fixed
