Hi,

I have two questions. These questions arise because I need to modify
'Test::Builder::TestPlan' to [ 'Test'; 'Builder'; 'TestPlan' ]. I'm
new to the project so I don't want to step on someone else's foot on
doing this.

1. The implementation of 'does' in src/ops/object.ops is as the following:

=item B<does>(out INT, invar PMC, in STR)

Sets result $1 to the result of the "does" vtable function for PMC $2,
given interface $3.

See L<tools/build/pmc2c.pl> for a list of available interfaces.

inline op does(out INT, invar PMC, in STR) :object_base {
  $1 = $3 ? $2->vtable->does(interp, $2, $3) : 0;
  goto NEXT();
}

Note the lack of '=cut' before the code. Is that intentional?

2. Can I add another 'does' implementation which accept PMC as $3 like
'isa'? This means adding 'Parrot_object_does' to src/object.c as well.
