Title: Suggestion for unless conditionals with code blocks.

I have a personal preference for not using ```unless``` with blocks. I personally find the ```if !condition``` option easier to read, but understand that's subjective.

I think the biggest win is that disallowing ```unless``` with blocks pretty much eliminates the possibility of writing ```unless/if``` conditionals.
