I don't follow. AFAIR my remark here above was about the STORE opcode. But you seem to react to it as if I am talking about STORE_FAST. > Could a rebinding operation *theoretically* be quicker for the other cases > which > involve a real dictionary (or something that looks like one)? Well, perhaps. > Although I can't see how the rebinding operation would gain a benefit that a > standard binding operation wouldn't gain if placed at the exact same point. Well it probably wouldn't be quicker, but it wouldn't be slower either as you asserted earlier. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
