Registering a PMC class works. Registering the same class a second time does not produce a diagnostic - although attempting to register a non-PMC class twice does.

Also, the second register produces some horrible results.

$nsp := Q:PIR {

P6metaclass.register('Key');

P6metaclass.register('Key');

_dumper($nsp);
