According to the CVS log, this implementation of docmp was installed in object.c 2.105, by gvanrossum, on 2001/01/17. What was the specific rationale for doing docmp in that order?

You can ask me directly, loewis. :-)

I believe that my thinking at the time was that tp_compare should only be used as a final fallback, just before comparing by address. This was consistent with my desire to completely get rid of tp_compare.

But until that is done, I now agree that it makes more sense to try tp_compare first when a three-way-compare is requested -- especially in the light of sequence comparison.
