It's _really_ not possible to use "else" without a huge BC break in
one form or another, something I'm trying to avoid at all costs.

Unfortunately that wouldn't help, we'd have to enforce braces on
everything (if/else/elseif/while/for/etc) to make it possible to hang
an "else" on the bottom of a loop, again a pretty big BC break.

I have actually discussed "braces everywhere" with several internals
devs, and the response has been pretty much unanimous: We'd like it,
but it will never pass the vote. It would be trivial to provide a
migration script though. Feel free to test the water with this idea ;)
