Apologies for previous code example. Yes, the 'def class' should read: 'class'.
Writing a sample to better demonstrate the issue made me realize that super()
is doing something special. It is injecting the magic '__class__' local.
I should rephrase my question: How do I get the declaring class

Python's attempt to solve the "external dependencies problem"

Hi
I needed a function f(x) which looks like sinus(2pi.x) but faster.
I wrote this one:

Well the fact is that RHEL 6 uses Python 2.6 as a core system package.

The principle of decorators themselves is as old as Python itself. You could
implement them as far back as Python 1.5, if not older:
