This module can play nicely with other constraint modules with some
slight tweaking. The C<where> clause in types is expected to be a
-C<CODE> reference which checks it's first argument and returns a
+C<CODE> reference which checks its first argument and returns a
boolean. Since most constraint modules work in a similar way, it
should be simple to adapt them to work with Moose.
