=head1 SYNOPSIS

  Moose::Util::MetaRole::apply_metaclass_roles(
      for_class => $p{for_class},
      attribute_metaclass_roles =>
          ['MooseX::SemiAffordanceAccessor::Role::Attribute'],
  );

=head1 DESCRIPTION

This role applies a method modifier to the C<_process_options()>
method, and tweaks the reader and writer parameters so that they
follow the semi-affordance naming style.
