  You can make members that have variable references, not just function 
pointers. For instance length is a static member of several classes that 
gets set to an integer value like this:

    obj->set_member("length",             length);

   If length was static or global, then it'd work the way you want it 
to. If the value of length changes after you've set the member, then 
yeah, it probably would only return the original value.

  The other way to do this would be to have length be a function 
pointer, and it'd just return the value of the same static data so you'd 
get the current value if it changed. If all classes use the same 
function pointer set to length, then they'd be sharing the data.
