Indeed, I just read this in Effective Perl Programming. I was shocked to discover that wrapping parens about a variable does NOT force it into list context. For the curious, the book lists as the only(?) way to force &foo into list context:  @{[&foo]}.

(that is, dereference an anonymous list of the item being forced to list context. See perlref for more on how referencing/de-referencing works.)

Anyone know WHY () doesn't work as the list version of scalar? I'm assuming there is either a good programming or perl innards practical reason, because I doubt that arturo and I were the only ones thinking this incorrectly.
