Oops. About that <op> thing, I was wrong. Though there is a case that does it:
sub bar();
sub postfix:bar($x) returns IO::Handle;
$x = length <bar>;
If it's possible to have a distinct sub and an operator with the same
name. If not, I believe the distinction is precisely the same as that
of named unary op with its argument optional. Except with infinite
lookahead. Ummm, okay, it's not possible. Because of less than and
friends, it's less possible than [op].
