In my odict implementation I have disallowed that syntax because if
you want to define a mydict(**kwds) function that allows a syntax
like:

mydict(a=6, b=7)

it takes a dict as argument, such dict is currently not ordered. If
built-in dicts become ordered, then that dict too may become
ordered :-)

Anyway, maybe it's good to ignore the inserting order of items when
you look for odict equality.
