That is what is currently done, but it isn't extensible. Ultimately, you need two - one streamlined to run a series of ops as fast as possible, and another to provide hooks for pre- and post- dispatch callbacks. That limits the number of opcode dispatchers for each variant to two, and allows arbitrary code (be it tracing, profiling, debugging) to be added to any of the variants. -- Bryan C.
