In the light of my recently discovered lemma, what I am about to say is
probably pointless, but being in a charitable mood I'll try anyway.
The set of provable statements about the circle is a simple consequence
of the Eucledean postulates (or their Hilbert's reformulation). As such,
the provable statements do not add any new information (or "behaviour")
to what is formulated by the third Postulate.
More interestinly though, your definition of behaviour is rather at odds with the accepted OOP use of the term as the collection of 'methods' of a specific class. Surely, an OOP practitioner should know better than that ! Received on Sat Feb 23 2008 - 04:02:34 CET
