Would that then imply that
sub blah { ... # 1 return if $a; # 2 ... # 3 }
...would return $a if $a was true, and fall through to (3) if it was false?
It sure should, provided there were a correct context waiting, which would
quite nicely address another WIBNI thread a couple of months back about a
quick return under those conditions.
I.... don't think so. I say that all the time to mean precisely:
if $a { return }
And I don't think people are ready to give that up.
In particular, if we kept our bottom-up parser around, this particular
construct would cause an infinite-lookahead problem. So for ambiguity's
sake, C<if $a> should not be a valid term without a block following.
So, just to make sure, these two lines are both valid, but do completely different things:
return if $a;
return if $a { $a }MikeL
