I want &-> because it's so understandable. People who haven't seen it would be able to guess what it does. That won't happen with ~> .

    Interesting - in contrast to your statement, I didn't understand the relevance of the ampersand until the very end of the discussion thread here and found its inclusion in the poll puzzling. I didn't read it as $bar *AND* call method method() on $bar; instead, I read it as the C "address-of" operator. Goes to show that what may seem understandable and intuitive to one person may not be at all for another.

      I guess you're right, the ampersand isn't so obvious.

      The problem is, reading the ampersand meaning address of could even make sense in perl. You could want an operator to create a bound method call, so eg. $object&->method creates a bound method like do { my $o = $object; sub { $o->method(@_); } }, and $object&&->method creates a bound method call weakly referencing the object.
