 Module::Loaded - mark modules as loaded or unloaded

SSYYNNOOPPSSIISS #

     use Module::Loaded;

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

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

$$bbooooll == mmaarrkk__aass__llooaaddeedd(( PPAACCKKAAGGEE ));; Marks the package as loaded to perl. “PACKAGE” can be a bareword or string.

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

$$bbooooll == mmaarrkk__aass__uunnllooaaddeedd(( PPAACCKKAAGGEE ));; 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.

$$lloocc == iiss__llooaaddeedd(( PPAACCKKAAGGEE ));; “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.
