[Python-ideas] A sorted version of **kwargs

Hi there python-ideas!
Does it bother anyone else that it's so cumbersome to instantiate an
OrderedDict with ordered data?
>>> from collections import OrderedDict
OrderedDict([('a', 2), ('b', 1)]) # Order lost. Boooo.
OrderedDict([('b', 1), ('a', 2)])
Obviously, OrderedDict's __init__ method (like all other functions) never
gets a chance to see the kwargs dict in the order it was specified. It's
usually faked by accepting the sequence of (key, val) tuples, as above. I
personally think it would be nice to be able to ask the interpreter to keep
track of the order of the arguments to my function, something like:
def sweet_function_name(*args, **kwargs, ***an_odict_of_kwargs):
I'm not married to the syntax. What do you think about the idea?
