I'm not sure we should expose the position-type to the SSA nodes.
I'm leaning towards "Dynamic sourceInformation" (after all, the SSA nodes don't
care at all, what is in there).
But I wouldn't be surprised if there are different opinions.
Maybe as compromise: Token sourcePosition; ?

OK, let's declare it as "Token sourcePosition" for now, it would be easy to fix
if anyone asks.

   static int idCounter;
