Hi,

assume you have a class with members (or member get/set functions) and want 
to call them by a string name with the least code to maintain.

I like to just have one macro line per member. The class should have a 
working assignment operator.

The end class should look like:

class foo
{
int bar;
int goo;

public:
...
int GetGoo()const {return goo;}
void SetGoo(int g) {goo = g;}
...

std::map<std::string, something_to_map_the_GET_function> getfunctions;

static std::string GetAllParams() {return std::string("bar,goo");}
int GetVar(std::string name) {return getfunctions[name] () ; }
};
