69 # ... or use a custom metaclass
70 # and custom attribute and method
72 use metaclass 'MyMetaClass' => (
73 'attribute_metaclass' => 'MyAttributeMetaClass',
74 'method_metaclass' => 'MyMethodMetaClass',

78 # and method classes, and Class::MOP::Class
79 # is the assumed metaclass

82 'method_metaclass' => 'MyMethodMetaClass',
85 # if we'd rather not install a 'meta' method, we can do this

90 This is a pragma to make it easier to use a specific metaclass
91 and a set of custom attribute and method metaclasses. It also
92 installs a C<meta> method to your class as well, if the
93 C<no_meta> option is not specified.
