Gets (or sets) the list of superclasses of the owner class.
-=head2 add_attribute Mouse::Meta::Attribute
+=head2 add_attribute (Mouse::Meta::Attribute| name => spec)
Begins keeping track of the existing L<Mouse::Meta::Attribute> for the owner
class.
Returns a mapping of attribute names to their corresponding
L<Mouse::Meta::Attribute> objects.
+=head2 get_attribute_list -> { name => Mouse::Meta::Attribute }
+
+This returns a list of attribute names which are defined in the local
+class. If you want a list of all applicable attributes for a class,
+use the C<compute_all_applicable_attributes> method.
+
=head2 has_attribute Name -> Bool
Returns whether we have a L<Mouse::Meta::Attribute> with the given name.
