 It depends on what kind of state we want to bring to the pushed
 source, but maybe.  I don't see the strong need for changing the
 current implementation, though.  The interface between the loader and
 lexer is mostly private, so if and when see specific reason for
 changing it we can do it without affecting actual users of the
 library.

 translated.

 Yeah good point, I was aware of that, too, but forgot it almost
 immediately:-)  I agree that the current approach is not ideal but I
 don't have an immediate nice solution to that.
