The most challenging aspect of inheritance modelling is to recognize it on its intrinsics - the deliberate creation of coupled properties and behaviors associated with the "isa" declaration - and not simply as a form of taxonomy. Programmers are still inclined to use hierarchies. They are implicit to source code in a more general sense, with indentation, nested logic, etc. But we also need affordances to break up hierarchies and keep them limited.
