I'd like to be able to have the operator of my class interact with regular types in a way that I define. Lets say, for example, I have:

class Mynum(object):
  def __init__(self, x):
   self.x = x
  def __add__(self, other):
   return self.x + other.x

a = Mynum(1)
b = Mynum(2)

print a+b

This works just fine, but now if I try to do:

print a+2

I get an error since an int does not have a member named x. How do I define Mynum + int in the class? This sounds like a job for decorators or metaclasses, but I'm terribly unfamiliar with their usage. This question seems similar, but not quite identical.
