Note that OO resuse is not the only theory of reuse possible.  Partial 
function application, higher order functions, modules and functors, 
universal types ('a), etc. also allow incredible code reuse, without 
touching objects.  In OO program, the object or class is the building 
block of reuse- in functional programming, it's the function.

If all you know is hammers, a cresent wrench is seen as a badly designed 
hammer.
