Regarding the special methods: decimal.py uses the optional context arguments
for convenience so that these methods can be re-used in other places.
I wouldn't consider this context argument as part of the API.

About this I'm not sure. I think type errors are a courtesy to the user.
Look what is possible now in decimal.py:
Decimal('9')
But here the argument might well be made for accepting None (and only
None apart from rounding modes). - I hope Mark and Raymond will give
their opinions, too.
