I'm really not a fan of

    do thing if condition

because to understand what it's doing I have to read it backwards.  
It's like the old Mark Twain joke about reading a German newspaper.

I'm guessing that's why Ruby doesn't have post-test loops either--to  
discourage "German sentence" programming.
