Is the issue that in foo(**{'a': 1, 'b': 1}) the 'a' and 'b' are
unicode and not acceptable as keyword arguments? I agree that should
be fixed, though I'm not sure it'll be easy.
I'm not sure you're saying that the optparse case shouldn't be fixed
in 2.6. or the foo(**{...}) shouldn't be fixed in 2.6, though I think
the latter.
