When you read OrderedDict([('a', '1'),('b', '2'), ('c', '3')]),

Creating an ordered dict from arbitrarily ordered input data surely ranks up there with one of the most pointless operations ever!
You know, this is such a simple, yet silly, mistake to make, I'd be almost tempted to disallow constructing an OrderedDict from regular dicts. If you want non-arbitrary ordering, you can't use a dict as input, and if you don't want arbitrary ordering, there's no point in using an ordered dict!
As far as I can see, there is no use-case for OrderedDict(dict) other than to generate confused newbies.
How about ['a':'1', 'b':'2', 'c':'3']?
Nice Idea!
I hope you're being sarcastic.
