• What does "Clear" mean to you?

Hi CheckiO members,

I've had/seen several conversations/debates in comments about which solutions should/n't be marked as "Clear". It seems to me that this question is bit controversial. The opinions about what "Clear" are quite different and I don't see any clear (:)) common sense meaning.

Therefore (and because I'm curious) I have a question for all of you:

What solution according to you should/n't be marked as "Clear" and why?

Thanks for participation!

P. S. I find a bit naive to use "clear" and "production code" in one sentence. The best (or worst?) examples of "anti-clear" code I've ever seen were in production code.
