That's just an implementation issue, though, and sounds like a minor
inconvenience to the implementor rather than anything serious;  I don't
think that that should dictate the API that's used.

- The API doesn't really feel very Pythonic to me. For example, we write:

And I guess this is subjective:  conversely, the API you're proposing
doesn't feel Pythonic to me. :-)  I'd like the hear the opinion of other
python-dev readers.

Thanks for the detailed replies.  Would it be possible to put some of this
reasoning into the PEP?
