You sometimes hear Ada refered to as "a 70's language." I sometimes
think of Eiffel as "an 80's language," since it forces one to program
using a "pure" object-oriented paradigm. What's so great about "pure"
object-oriented programming, anyway?
Not having done any programming in Eiffel, I'm not going to comment on
the design of that language, but I agree that object-oriented
programming is only one tool among many that a programmer should have at
his disposal.
The OO hype left over from the 80's hasn't quite subsided, but the tide
is turning. People are finally beginning to realize that using (public)
inheritence to compose abstractions creates too many dependencies, which
can stymie the growth of a large system in development.
Indeed, the debates about the "proper" taxonomy for an inheritence tree
are redolent of the debates we had in the 70's about what the "proper"
decomposition of functions should be. This is ironic, since the
object-oriented paradigm was intended to silence those debates!
Creating deep (public) inheritence hierarchies, though typical in "pure
OO" languages, is definately not a technique that should be used in
Ada95 or C++, where objects have value semantics. Another thread on
this list has alluded to the better way, using "closed" abstractions
that use inheritence as a private, implementation mechanism.
