Q: Can you call 'f' with keywords that will be

no.
OK. Thank you for an answer.
what's the use case?
I have extended the dict class, so that my __getitem__ accepts an
optional parameter
[...]
But it still doesn't guarantee that __getitem__ accepts keywords.
(What if somebody will extend the Tree class and overlook the
definition of __getitem__ and define a "classic" one)
Then they haven't programmed to your API, and deserve to be rewarded
with an error message - it's the only way they can be informed they
aren't writing to your standard, surely?
