This is a no-op, which takes time to execute but indeed doesn't seem
to disable the optimization. However I don't see the point. You may
as well write it like that:
def __init__(self, x, y, z):
d = self.__dict__
d['x'] = x
d['y'] = y
d['z'] = z
It is a bit slower than "self.x = x; self.y = y; self.z = z" in PyPy
but doesn't throw away the optimization. On CPython it is probably
faster.
