FWIW, having the function dispatch table as the default case in a switch
wasn't a big win in my initial testing. The savings came from an initial
test to decide to switch or lookup, but that requires the non-overrideable
to be blocked so that they're easily tested (ie, opcodes 0-n). Parrot's
performance does seem to differ from my initial testing, though, so you may
want to benchmark it every which way.
