libclass-load-perl - 0.25-1 main

"require EXPR" only accepts Class/Name.pm style module names, not
Class::Name. For that, Class::Load provides "load_class 'Class::Name'".
.
It's often useful to test whether a module can be loaded, instead of throwing
an error when it's not available. For that, Class::Load provides
"try_load_class 'Class::Name'".
.
Finally, sometimes it is important to know whether a particular class has
been loaded. Asking %INC is an option, but that will miss inner packages and
any class for which the filename does not correspond to the package name. For
that, this module provides "is_class_loaded 'Class::Name'".
