       case the version and authority.

INHERITANCE
       [Class::MOP::Module](https://www.chedong.com/phpMan.php/perldoc/Class%3A%3AMOP%3A%3AModule/markdown) is a subclass of [Class::MOP::Package](https://www.chedong.com/phpMan.php/perldoc/Class%3A%3AMOP%3A%3APackage/markdown).

METHODS
   [Class::MOP::Module](https://www.chedong.com/phpMan.php/perldoc/Class%3A%3AMOP%3A%3AModule/markdown)->create($package, %options)
       Overrides "create" from [Class::MOP::Package](https://www.chedong.com/phpMan.php/perldoc/Class%3A%3AMOP%3A%3APackage/markdown) to provide these additional
       options:

       "version"
           A version number, to be installed in the $VERSION package global
           variable.

           variable.

           This is a legacy field and its use is not recommended.

   $metamodule->version
       This is a read-only attribute which returns the $VERSION of the
       package, if one exists.

   $metamodule->authority
       This is a read-only attribute which returns the $AUTHORITY of the
       package, if one exists.

   $metamodule->identifier
       This constructs a string which combines the name, version and
       authority.
