[Numpy-discussion] abstraction and interfaces

[Matthieu Brucher]

What is more, with the concept of duck-typing, you just have to provide the
interface without inheriting from a mother class (which is what I do for the
optimizer framework, the other sub-modules do not derive from a common
ancestor).
