I think of these, y = list(x) is probably the "right" way.
Actually, x[:] has always been standard, and is faster, at least for
short lists:

Possibly, but it assumes x is a list. For non-list objects a slice can
actually return a view of the original. list(x) ensures a shallow copy
that is a list. It also works with any iterable x.
