Ahh, that did it. I didn't even think of calling object...
so the new class looks like:
class Spam(object):
cache = {}
def __new__(cls, x):
if cls.cache.has_key(x):
return cls.cache[x]
else:
new_Spam = object.__new__(cls, x)
cls.cache[x] = new_Spam
return new_Spam
def __init__(self, x):
self.x = x
a = Spam(2)
b = Spam(2)
a == b # => True
id(a) == id(b) # => True
Thanks for all your help.
