Sorry; I've just been really busy on other things.  I'm on python-dev
these days, though I skim the messages very quickly.

I wish you were wrong on this, but I don't think you are.  ;-(

Yeah, not too pretty.

For things like this, where some manner of dispatch is needed based on

there's a real problem associating the right bit of code, and I'm
quite torn as to the right approach to take.  ;-(
