=head2 meta

A flag method that always returns 1. This can be used in e.g. POE to check
if the class supports L<Data::Transform::Meta>, which all Data::Transform
subclasses should, but L<POE::Filter> classes don't. Doing it this way
instead of checking if a filter is a Data::Transform subclass allows for
yet another filters implementation that is meant to transparently replace
this to be used by POE without changes to POE.
