p5-Class-Load-0.25p0

"require EXPR" only accepts "Class/Name.pm" style module names, not "Class::Name". How frustrating! For that, we provide "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, we provide "try_load_class 'Class::Name'". Finally, sometimes we need 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, we provide "is_class_loaded 'Class::Name'".
