In the reference implementation, it's just DUP_TOP followed by
STORE_FAST (well, technically by "whatever the assignment compiles

there much advantage to creating a new opcode?
Probably not much, but I thought we now lived in an age of wonders where
common sequences of opcodes were getting mashed together into new
more-complicated-but-redundant bytecodes (e.g.
BUILD_MAP_UNPACK_WITH_CALL) just to save on dispatch overhead. You're
right, it'd be a micro-optimization, and its value would be debatable.
