In short, I really don't think there's a need for context variables to be faster than instance variables. There really is: currently the cost of looking up a thread local through the C API is a dict lookup, which is faster than instance variable lookup, and decimal and numpy have both found that that's already too expensive. Or maybe you're just talking about the speed when the cache misses, in which case never mind :-). -n
