Any chance to pass an Action via an Event

Probably this is more a general C++ question than it is a tinyfsm one, but maybe somebody did this already.

I have an event called ShouldEstimateAndSend which transits to a new state on a few conditions. I'd like to have it call transit\(ShoudEstimateAndSend::action_function).
Using std::function would work, but this introduces some runtime overhead and pulls in exception handling which is not what I like on my embedded target. Using a template event class 'breaks' inheritance and would need a template react function as far as I can see?!

Can't wiggle my head around this.
