Re: [boost] [Function] Interest in boost::functions that take and return references to self-type?

If state machines are what you're after have a look at Boost.Statechart http://www.boost.org/doc/libs/1_40_0/libs/statechart/doc/index.html or (soon to be reviewed) Boost.MSM in boost vault http://www.boostpro.com/vault/
