"""A function model represents the model of a Ceylon function that you can invoke and inspect.
   
   A method is a member function: it is declared on classes or interfaces.
   
   This is both a [[FunctionModel]] and a [[Member]]: you can invoke it with an instance value
   to bind it to that instance and obtain a [[Function]]:
