To get correct file positions in debugging code and error messages.
So every temporary change of current_tokenpos should be considered
wrong? According to your above description I'd make current_tokenpos a
read-only property of the scanner...
I'am not sure what e.g. generics do with it.
Generics need to replay tokens with their position for debugging purposes.
