Description:

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.

The test suite here is not complete, although it does verify a few basic
things. The best testing comes from running the Class::C3 test suite *after*
this module is installed.

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).
