Anyone have any idea how efficient the switch statement is for very large case-sets, e.g. 500 cases? I'm hoping the compiler comes up with intelligent ways of performing the required conditionals, and doesn't just expand the switch out to a bunch of if..else's...

In this particular case I'm switching on a uint32, so it wouldn't be too much trouble for me to break it down into if's and smaller switches, if necessary.

Why don't you just look at the generated assembly, and see for yourself?
