[swift-evolution] [Idea] return if / return unless

[Kurt Werle]

Why would you do this just for return statements?  Why not do postfix
conditionals for all statements (like ruby)?

I've always liked postfix conditionals, but not enough to suggest them.
Mostly I'm curious about limiting the scope to return statements.
