Maybe it also makes sense to use indexing into a static array, instead of the case construct. Note that there can be one single such table for all opcodes and all cases, since opcodes are still disjoint. It depends where this table is stored and if this can get in the cache.
While I don't know if this really makes the interpreter more efficient, at least it makes it shorter to read and maybe easier to maintain.
Been there, done that: http://python.org/sf/693638 I already rejected the patch. :-) Making my own jump table, rather than using a switch was about 15% slower. Read the patch for more info. While I'm sure the patch could be improved, I don't think it would have made enough of a difference to make a change. Neal
