In python 2
map
already returns a list, and as far as I know (and as checked for 3.5) in python 3 any iterable can be unpacked on assignment.list()
calls from unpacking assignments of the formx,y = list(map(fun,seq))
.list(map())
where the resulting object is directly consumed by anothermap
call on the next line. Considering how this change is qualitatively different from the other, more trivial ones, I separated this change for ease of cherry-picking if necessary.
