Sorry @Sara - didn't reply to all the first time.

mind === blown
This would open up a huge amount of other functionality I'd never
dreamed of (some of which is quite scary!)
for($i = for(...) {}; $i < ...) {}
I'm really not sure I understand the full implication of this though.
This would mean changing loop constructs from statements to
expressions. I wonder how difficult that will actually be, and what
other problems it would cause (I obviously haven't played with this
idea yet).
It would also mean having to make { default block } into an
expression... with a return value (to be allowed on either side of the
boolean or)
Lots to think about here, if it's at all viable this will need it's
own separate RFC, it's a much more invasive change, but definitely a
great idea.
