You lose the ability
a) To use a function *object* which contains state
Is this correct? Isn't, e.g., a bind expression already a function object
that contains state? Or do you mean that you loose the ability to access
the
state of such a function object?
Thanks,
Cheers,
Yes, I meant accessing the state of such a function object.  With arbitrary
functors you can provide arbitrary state that can be modified by operator()
of the visitor.  After the call to apply_visitor(), you can access this
state.
