This is true AFAIK too.

IIRC, copy once used to, but stopped doing so when I realized that we 
morphed...and then copied right over whatever morph might have produced. :-)

FWIW, I've yet to find a use case for morph in anything I've done in 
Rakudo. Between the copy op and our rebless_subclass dynop, we've got 
what we've needed to date.

I'm curious - is anyone else doing a HLL on Parrot that uses morph? If 
nobody is, is it worth spending time on, or even worth keeping?

Thanks,
