yes, but with parens, it *is* a call:
sub foo(...) {...}
say &foo(...); # Calls &foo
say foo(...); # Calls &foo
say &foo; # "CODE(0x....)" or somesuch
(FWIW, I agree with Matt, but Juerd's ./method is nice, too. And we
shouldn't forget that Perl 6's OO is *far* more than that "method on
self" thing. I favour .method meaning $?SELF.method, but this only a
very minor issue when comparing with roles, autogenerated accessors,
anonymous roles|classes, parameterized roles, etc. :))
