Couldn't you have a single opcode, C<assign_content Pn, Pm>, which uses
Pn's vtable assignment, and make C<add $P1, $P2, $P3> etc simply use
the 'make a new PMC' thing. That means that, to get the current
semantics you'd have to do
$P2 = $P3 + $P4
assign_content $P1, $P2
But I'm not sure that's an enormous loss.
