PEP 372 -- Adding an ordered directory to collections

[Paul McGuire]

:)

Yes, I thought about that even as I was writing that post.  But I also said,
"ParseResults implements quite a bit of additional behavior that would not
be required or necessarily appropriate for  odict."  Even if odict existed,
I think I would have needed ParseResults anyway (but using an odict
internally might have simplified things for me, instead of the combined list
and dict that I have now).

Paul,

You seem to be contradicting yourself.  You may have never needed an odict,
yet you seem to have implemented one on your own.  Maybe you needed one but
did not realize it?
