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): pass
I'm not married to the syntax. What do you think about the idea?
I would be +0 on making **kwargs an ordered dict automatically, and -1 on adding ***ordered_kwargs. Because kwargs is mostly used only for argument passing, and generally with only a small number of items, it probably doesn't matter too much if it's slightly slower than an unordered dict. But adding a third asterisk just makes it ugly, and it leaves open the question what happens when you try to mix **kw and ***okw in the same function call, as you do above. -- Steven
