With any minimally optimizing compiler, yes it does.
Ok, thanks for the hint, I am quite happy now. This is the final argument against the class per bytecode, this can't be done much faster as far as I see.

I have just testet gcc with a -S, and with a few cases in the switch, it generates the code I feared, but as I add up entries, the code gcc makes change to a nice label array, even if not optimizing.
