Here's a question (actually, three questions) for python-dev that came up in the issue 1717 (removing cmp) discussion.
Once the cmp removal is complete, the type object's tp_compare slot will no longer be used. The current plan is to rename it to tp_reserved, change its type to (void *), and raise TypeError when initializing any type that attempts to put something nonzero into that slot. But another possibility would be to remove it entirely. So... Questions: (1) Is it desirable to remove tp_compare entirely, instead of just renaming it? (2) If so, for which Python version should that removal take place? 3.0.1? 3.1.0? 4.0? and the all-important bikeshed question: (3) In the meantime, what should the renamed slot be called? tp_reserved? In the issue 1717 discussion, Raymond suggested tp_deprecated_compare. Any thoughts? My own opinion is that it really doesn't matter that much if the slot is left in; it's just a little annoying to have such backwards-compatibility baggage already present in the shiny new 3.0 series. A little like finding a big scratch on your brand-new bright yellow Hummer H3. Or not. N.B. The same questions apply to nb_reserved (which used to be nb_long) in the PyNumberMethods structure.
