int (or char), so you can't turn a CFSWITCH into a Java switch unless the
_expression_ is an int. I'm obviously not privvy to the CF codebase, but
that's a language limitation that's been there since the beginning.
Or were you refering to the chaining stuff? Again, I've not seen source,
but I can't think of a good reason to evaluate all the criteria when you
don't have to. Same thing as short-circuit boolean operations within a
single boolean _expression_.
