[swift-evolution] Hidden initiallizations ...

> 		else { /* Do some other stuff */ }

Interesting! :-) I should explore this, sounds fun in some cases.

I typically just use the bare word:

for value in values {
  if let value = value {
    foo(value)
  }
}

...but sometimes that clashes with an argument or field, and yours could be a good convention to resolve those cases.
