This contains XS performance enhancers for Class::C3 version 0.16 and higher. The main Class::C3 package will use this package automatically if it can find it. Do not use this package directly, use Class::C3 instead. This module won't do anything for you if you're running a version of Class::C3 older than 0.16. (It's not a dependency because it would be circular with the optional dep from that package to this one).
