​This one won't work, because it looks like in-place multiplication
(__imul__) which clashes with the above for a single name as assignment
target:

x *= 2  # "x = x * 2"

Consuming does not contradict with your proposal, but maybe you mean *fully
consuming*. I think you are proposing partial or incremental consumption of
the rhs.
