The would likely take an API change. For now, using only what is already
exposed in Python, we can only partition data descriptors in two groups:
* Known to be readonly because __set__ is missing or fset is None
* Possibly writeable, can't really tell until __set__ is called
Example in the latter category,
>>> t = time.localtime()
>>> hasattr(type(t).tm_sec, '__set__')
True
>>> t.tm_sec = 31
Traceback (most recent call last):
File "<pyshell#23>", line 1, in <module>
t.tm_sec = 31
AttributeError: readonly attribute
