Versus _.tolist(), which would also overwrite the previous return value?

array has had that method since before Python v1.0. memoryview, for
whatever reason, is not iterable; parser.ST is also not, since it
doesn't convert to a flat sequence but rather a list tree.  I don't
see the special case for dict views, at all.
