Use PyStructSequence for result() return value #61
Description
The result/result2/result3/result4 API looks quite silly by today's standards, if you don't mind me saying.
Do what os.stat does. result() should return an object that:
- for backwards compatibility, acts like a tuple of the first two elements
- has everything accessible as attributes.
Such a type can be defined at the C level using Struct Sequence.
In Python 2 this API is private; use a regular namedtuple subclass?
Deprecate result2/result3/result4 (but keep them around indefinitely).
