119
120Class::MOP::Method::Inlined - Method base class for methods which have been inlined
121
122=head1 DESCRIPTION
123
124This is a L<Class::MOP::Method::Generated> subclass for methods which
125can be inlined.
126
127=head1 METHODS
128
129=over 4
130
131=item B<< $metamethod->can_be_inlined >>
132
133This method returns true if the method in question can be inlined in
134the associated metaclass.
135
136If it cannot be inlined, it spits out a warning and returns false.
