Oh, perhaps I didn't state it correctly. You can avoid braces, but not if you want to use if/elsif/else/unless/etc. which require them:
condition && do_this(); condition || do_this(); condition ? do_this() : do_that();
(and others I can't recall right now)
But my point was only that it's always possible to get around these artificial restrictions; it's more important to ask for legible sensible code. Sorry if that was unclear!
