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.
