IMO someone like you probably *should* vote against it, especially if
you've taken the time to do reasonable review.  At least you have a
real-world need for FSMs.  I just "know" that FSMs are sometimes used
for lightweight speed-critical components.  Or maybe more people
should be voting for it on the *condition* that an option with fast
dispatch must be available.  I must say, in a world replete with
high-performance generic components, I agree that "Boost FSM" is too
broad to cover a library that only does dynamic double-dispatch.
