Second, a "metaclass" to add a number of methods (or other attributes) to an existing class, using a convenient class notation: ... class (): metaclass = monkeypatchclass def (...): ... def (...): ... ...
In Objective-C it's perfectly common to extend existing classes using
'categories' and I have often found this idiom very useful. What is
described here is basically categories for Python. I've implemented
something like this before and I would be happy to see this added to
the standard library and formalised.
