- This is silly. This even proves what piercarlo was saying is wrong because
- piercarlo claimed such references are not polymorphic. Meyer clearly agrees
- with me, um, I mean I clearly agree with him on this.

- Boy did you get this one wrong. After posting, I looked up the definition
- of polymorphism in the old Webster's. I hate to tell you this, but
- polymorphism has been well defined as referring to objects that can
- assume different forms long ago (its the literal translation, for God's sake).
- Sorry I don't have the dictionary here with me or I'd quote it for you. The
- sciences are using the standard definition, if anyone really got away from it,
- it was Strachey (and current followers) in his notes in passing, which is
- obvious!

- P.S. Are there any other true object-oriented followers out there? There
- seems to be lots of functional ones...
