The return value of to list() is an int, not a list.
That's because NumPy's tolist() does the same thing:

x = numpy.array(120, dtype='B')
x
array(120, dtype=uint8)
x.tolist()

If you implement tolist() recursively like in _testbuffer.c and choose
the zeroth dimension as the base case, you arrive at single elements.
So at least it's not completely unnatural.
