GPA, but here goes:
Though inheritance is usually needless complexity, and functional programming
with ADTs is the One True Way, using packages in Perl *is* still very
convenient. It lets you push the functions on your ADT into the namespace of
that package, instead of having one huge function namespace. So instead of
oparate_on_foo($foo) and operate_on_bar($bar), we can just say
$foo->operate() and $bar->operate(). This ends up making your code more
terse, making the logic more obvious.
