PEP 246... Why does Python have to support every pattern out there?

Here I go again with my complaints about the recent PEPs.While I understand the value of bi-directional adaptors, I really do notsee the reason for adding support for this pattern to the language.Here are my reasons:1. This pattern can be implemented as a stand alone base class.2. The definition of the interface/context is very vague. This limits theability to clearly identify the interfaces.3. I am also worried about the versioning problems. COM resolves thisproblem by uniquely identifying each version of each interface with aGUID. Java resolves the problem by using unique class names. Are theregoing to be any rules for versioning here?4. Do we know how often this feature will be used? Why not create a modulethat implements the pattern and see if it is being used. And only thenpossibly migrate the feature into the language. This worked well forPyUnit.-- Alex Shindichmailto:alex at shindich.comVisithttp://www.shindich.com/
