In order for that to be an equivalently obvious form one would need to
adopt an indentation convention that caused the exit test to stand-out
as well as the top and the bottom of the loop do.  Probably not hard,
especially with colored-syntax editors (environments?), but not a
current standard. (Well, at least not one that I know.)
