I didn't understand your suggestion completely. Could you post the resulting hierarchy after adding alien-doctor bill. Below is the original class hierarchy, prior to encountering alien-doctor bill.

human

__engineer
____bob
__doctor
____sue

I did not assert is-a relation is indirect. I asserted that there is an indirect/derivable, but not direct, relationship between classes human and doctor. I prefer to withdraw this assertion as it will likely become an end-less discussion involving the definition of indirect/derivable, direct, relationship, etc. Received on Tue Apr 11 2006 - 23:19:01 CEST
