Please recognize that our little system of patches and newsgroup
discussions is easily overwhelmed by someone who is so prolific.
Your work will not receive quality review and discussion if the
volume blows beyond the bandwidth of the other participants.

Arghh! You seem hell-bent on jamming this in. Please leave the
decimal module alone. It does *not* need both a round() method
and a quantize() method.
I read Glyph's note and agree that it wasn't obvious how to round
with the existing API. That is a documentation problem, not a call
to add duplicate methods.
When one of the module authors asks you to refrain for expanding
the API, please pay special attention. In this case, you are working
directly against a core philosophy for the design and maintenance
of the module.
I admire your enthusiasm, but please hold it in check.
