Yes, but sometimes you need logic that takes place on all exits from a state, on all entries to a state, or even form a hierarchy of nested state. Often there's more "state" involved (like accumulating intermediate values) and a switch statement isn't friendly to scoping that.

I love writing switch statements (even with gotos) for small things like lexical analyzers, but when it comes to maintainability and extensibility, a well-designed framework is the way to go.

The Boost C++ libraries supply two of them. I've used one of them and am eying the other. They claim its template magic can make the result actually faster than a typical switch-driven design.
