I think a better example is : $ perl -e '$_ = ($foo) = (1,3); print' 2 versus $ perl -e '$_ = $foo = (1,3); print' 3 There you can see how () was useful, and be reminded that a list in scalar context returns its last element. -- Philippe "BooK" Bruhat The right answer is worthless with the wrong question!
