I recall a claim that

is the most efficient way to get one result.
I'd never expect that for-loop assignment is even faster than a
precreated iter object (the second test)... but I don't think this
for-looping variable leaking behavior is guaranteed, isn't it?
It is an intentional, documented feature:
"Names in the target list are not deleted when the loop is finished, but
if the sequence is empty, it will not have been assigned to at all by
the loop."
