=head1 PURPOSE
Compares the speed of the constructor in four equivalent classes built
using different tools:
=over
=item B<Moo_MXTML>
L<Moo> with L<MooX::Types::MooseLike::Base> types and non-L<Sub::Quote>
coderef coercions.
=item B<Moo_TT>
L<Moo> with L<Type::Tiny> types and coercions.
=item B<Moose>
L<Moose> with L<Moose> type constraints and coderef coercions. Class is made
immutable.
=item B<Moose_TT>
L<Moose> with L<Type::Tiny> type constraints and coercions. Class is made
immutable.
=back
=head1 RESULTS
For both Moose and Moo, L<Type::Tiny> type constraints are clearly faster
than the conventional approach.
