I think it should be both.
my $foo = {};
$foo(); # It was a sub
my $foo = {};
$foo<bar> = 1; # It was a hash
It's not as if we're allergic to intelligent autovivifithingy... :)

Why? Doesn't while's signature specifically prescribe a sub there, and
if it does, then wouldn't it be just a bit too silly to stick to {}
being a hash?
