I thought I had already indicated:
- that a heavily overloaded method indicates a missing abstraction 
- that Source is not ideal, but a better basis for evolution than a
class with a heavily overloaded method.
So if it's day 1 of iteration 2, then I suggest starting out from Source
not polymorphism .
 strictly speaking, there's a responsibility that ought to be
encapsulated within an object, but currently is not.
