The features are centred around the function cv_set_call_checker, which allows XS code to attach a magical annotation to a Perl subroutine, resulting in resolvable calls to that subroutine being mutated at compile time by arbitrary C code. This module makes cv_set_call_checker and several supporting functions available. (It is possible to achieve the effect of cv_set_call_checker from XS code on much earlier Perl versions, but it is painful to achieve without the centralised facility.)
