You note said: "I'll implement Context.round() in a separate patch. Comment away." Oh, sorry for not being clear then. I don't intend to write or discuss that separate patch until this one's approved and submitted. I think it's worth discussing eventually, but this change is more important. I mentioned this sentiment at http://bugs.python.org/msg59417 too, but clearly wasn't explicit enough in either case.

It's hard to keep up with all of these patches and I'm growing concerned that some will sneak by. In the case of complex proposals, it is often helpful to have a patch that we can discuss concretely, but in the case of simple ones like this, they just clutter to patch tracker. There's no need to create the patch until the idea has been discussed.

In the case of Context.round(), I've already advised against it. So, I'm not sure why you still intend write a separate patch and bring it back up for discussion. Ideally, it should die right now.

The sentiment is unchanged -- please do not build-out the API for the decimal module. It is intended to be minimal and needs to stay that way. Further additions will only make it harder to use, harder to maintain, and will complicate efforts to rewrite the module in C.
