So the problem is that there are two pairs of two in:

$ perl -lwe 'sub foo { my $q = sub {}; ($q, $q) } my @a = foo(); my @b = foo; print "@a / @b"'
CODE(0xfdd84) CODE(0xfdd84) / CODE(0xfdd84) CODE(0xfdd84)

but currently it's not clear which they are :-)

I like the idea of the real copies but shared scratchpads. I hope it's viable.
