Method modifiers are a powerful feature from the CLOS (Common Lisp Object
System) world.
In its most basic form, a method modifier is just a method that calls
$self->SUPER::foo(@_) . I for one have trouble remembering that exact
invocation, so my classes seldom re-dispatch to their base classes. Very
bad!
Class::Method::Modifiers provides three modifiers: before , around ,
and after . before and after are run just before and after the method
they modify, but can not really affect that original method. around is
run in place of the original method, with a hook to easily call that
original method. See the MODIFIERS section for more details on how the
particular modifiers work.
