Here's a proof of concept. I use a class with a custom metaclass like this:
# Python 3 version
class ExampleNS(metaclass=Namespace):
x = 1
y = []
def spam(n):
return 'spam'*n
py> Example.spam(5)
'spamspamspamspamspam'
Why not just extend the capabilities of a class? I actually thought this
would work until I tried it and it didn't:
class C():
def fn():
print ("Hi!")
C.fn()
The error message suggests Python knows what's going on. So why not just
make it work?
(The main issue would be, if an instance X of C /was/ created, then
X.fn() wouldn't work as there is no 'self' parameter for fn.)
