I've been thinking about Python performance improvements, and I played around with an inline cache enhancement that supports slots. The results on a very simple benchmark look promising (30% speedup) but I'm terrible with our benchmarking tools, and this should be considered very carefully before we go ahead with it, since it could potentially pessimize the inline cache for standard attributes. I'll attach a PR in a minute.

I've been thinking about Python performance improvements, and I played around with an inline cache enhancement that supports slots. The results on a very simple benchmark look promising (30% speedup) but I'm terrible with our benchmarking tools, and this should be considered *very* carefully before we go ahead with it, since it could potentially pessimize the inline cache for standard attributes.

I'll attach a PR in a minute.
