=head1 NAME

Class::MOP::Method::Inlined - Method base class for methods which have been inlined

=head1 VERSION

version 2.2013

=head1 DESCRIPTION

This is a L<Class::MOP::Method::Generated> subclass for methods which
can be inlined.

This method returns true if the method in question can be inlined in
the associated metaclass.

If it cannot be inlined, it spits out a warning and returns false.
