libdevel-callchecker-perl - 0.008-1+b2 main

Devel::CallChecker makes some new features of the Perl 5.14.0 C API
available to XS modules running on older versions of Perl.
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.)
