# This is what I have in mind:
class Item(object):
def __add__(self, other):
return Add(self, other)
class Add(Item):
def __init__(self, a, b):
self.a = a
self.b = b
a = Item()
b = Item()
c = a+b
# Now, I am going absolutely crazy with this idea
# and using it in a big way. So I'm looking at
# automating the process. As a first step,
# I thought maybe this would work:
class Item(object):
pass
class Add(Item):
def __init__(self, a, b=None):
print self, a, b
self.a = a
self.b = b
Item.__add__ = Add
x = Item()
y = Item()
print x, y
c = x+y
# This time, the Add constructor gets only the first two arguments:
"self" and "y".
# So, what happened to "x" ? Is this some kind of property voodoo going
on ?
