digitalmars.D.learn - getting the adress of a function by its name in string format

I would like to use json/or any other format for defining 
behavior trees.
in that file format I can only use strings

currently I just use the symbol directly but I was wondering how 
to 'find' them otherwise.


float EAT_FOOD_DECISION(Agent agent){
     return 1.0 - agent.hunger;
}
bool EAT_FOOD_BEHAVIOUR(Agent agent){
     agent.hunger -= 0.1;
}

auto eat_food = Behaviour(&EAT_FOOD_BEHAVIOUR);
auto eat_food_decider = 
Decider(DeciderType.Behaviour,&EAT_FOOD_DECISION[],eat_food);

instead I would like to use "EAT_FOOD_DECISION" and 
"EAT_FOOD_BEHAVIOUR" and get the functions?

Is that possible somehow?

If all your functions had the same signature, you could use an
associative array  FunctionType[string] and initialize it:

FunctionType[string] myFuncs;
myFuncs["EAT_FOOD_DECISION"] = &EAT_FOOD_DECISION;

But it seems they have different types?

I think that is the best solution indeed, there are only two 
types(BevaviorFunc and DeciderFunc), so two dictionaries instead.

It also solves another issue of not having strings for naming the 
functions in logs.
