The "mro" namespace provides several utilities for dealing with method
resolution order and method caching in general in Perl 5.9.5 and higher.
This module provides those interfaces for earlier versions of Perl (back
to 5.6.0 anyways).
It is a harmless no-op to use this module on 5.9.5+. That is to say,
code which properly uses MRO::Compat will work unmodified on both older
Perls and 5.9.5+.
If you're writing a piece of software that would like to use the parts
of 5.9.5+'s mro:: interfaces that are supported here, and you want
compatibility with older Perls, this is the module for you.
