  Ah.  Derivation/inheritance.  Didn't allow for that.

  Ah, no, but since there's implicit concatentation of strings going on there
by having one private print routine call the other... argh.  Yeh, can't be
done; best just let them parse the words themselves.  Ah well, it would have
been nice - but only if it had been practical and simpler than the alternative!
