in thread To & or not to & ?

Note that, & only passes @_ IF you leave off the parens.

So that, if bar was implemented

sub bar { &foo(); }
then it wouldn't pass anything at all to foo. So, &FUNC should be considered a different way to call than &FUNC(), because only one of them does something different than FUNC()
