You might use a separate prime generator to produce prime factors. The
factorize algorithm becomes quite simple and configurable by prime
generators. For demonstration purposes I use the eratosthenes sieve.
def eratosthenes():
memo = {}
q = 2
while True:
p = memo.pop(q, None)

For a workaround you simply have to "mangle" those using an escape

Hi Steven,
Just reasoning about conversion of classic to new style classes (
keeping deprecation of ClCl in Py3K in mind ) I wonder if there is a
metaclass that can be used to express the semantics of ClCl in terms of
new style classes? Intuitively I would expect that there is quite a lot
of Python semantics

The problem of unintended inheritance is typical for OO frameworks and
can be explained as follows. Given a class Foo implemented by Alice and
a derived class Bar of Foo implemented by Bob. Bar implements a method
