Ever notice inheritance is that concept every programmer learns but rarely

Inheritance is just too weird and brittle to be much use in the real world.
Anyone's mileage vary?
I find it depends a lot on the language you are using, actually. Using a
deep hierarchy effectively in C++ is quite difficult and painful, but in
Smalltalk it seems quite natural.
I know it sounds counter intuitive that a programming language would
effect how you design your objects, but it just does.
That said, even a 1 level deep inheritance hierarchy can be a powerful
tool. I'm not sure why you would imply that it was something less than
using inheritance.
