       Module::Loaded - mark modules as loaded or unloaded


           use Module::Loaded;

           $bool = mark_as_loaded('Foo');   # is now marked as loaded
           $loc  = is_loaded('Foo');        # location of set to the
                                            # loaders location
           eval "require 'Foo'";            # is now a no-op

           $bool = mark_as_unloaded('Foo'); # no longer marked as loaded
           eval "require 'Foo'";            # Will try to find in @INC


       When testing applications, often you find yourself needing to provide
       functionality in your test environment that would usually be provided
       by external modules. Rather than munging the %INC by hand to mark these
       external modules as loaded, so they are not attempted to be loaded by
       perl, this module offers you a very simple way to mark modules as
       loaded and/or unloaded.


   $bool = mark_as_loaded( PACKAGE );
       Marks the package as loaded to perl. "PACKAGE" can be a bareword or

       If the module is already loaded, "mark_as_loaded" will carp about this
       and tell you from where the "PACKAGE" has been loaded already.

   $bool = mark_as_unloaded( PACKAGE );
       Marks the package as unloaded to perl, which is the exact opposite of
       "mark_as_loaded". "PACKAGE" can be a bareword or string.

       If the module is already unloaded, "mark_as_unloaded" will carp about
       this and tell you the "PACKAGE" has been unloaded already.

   $loc = is_loaded( PACKAGE );
       "is_loaded" tells you if "PACKAGE" has been marked as loaded yet.
       "PACKAGE" can be a bareword or string.

       It returns falls if "PACKAGE" has not been loaded yet and the location
       from where it is said to be loaded on success.
