I wonder if the recent things you've been thinking about should be combined. Namely: make a PMC wrapper for the interpreter. Then do constant table manipulation through method invocations on the interpreter PMC. Or if not methods, then whatever mechanism you end up with for doing L-U decompositions for Josef H.'s matrix PMCs. While we're at it, we could nuke interp_info and do that through keyed access to the interpreter PMC.
