hmm

Thinking abstractly, inheritance is a perfectly valid way of 
implementing composition. In fact, we can look on inheritance as the 
purest form of composition (in an Object Oriented paradigm). An instance 
of a subclass cannot exist without the superclass extant, the subclass 
is (in part) *composed* of the superclass.

How do you 'distinguish between composition and inheritance'?
(as opposed to distinguishing between composition and aggregation)
they are two entirely different (but ultimately, often connected) concepts.

I do agree that the OP has a somewhat 'unique' way of putting his/her 
ideas across to say the least.
