libclass-method-modifiers-perl binary package in Ubuntu Oracular amd64

 Class::Method::Modifiers provides three modifiers: before, around, and after.
 The before and after modifiers are run just before and after the method they
 modify, but cannot really affect that original method. The remaining modifier,
 around, is run in place of the original method, with a hook to easily call the
 original method.
