It seems this is a more general way to build classes than inheritance.
Is this a reasonable viewpoint?
>>>
>>> def meth1(self):
... print "i am meth1"
...
>>> def meth2(self):
... print "i am meth2"
...
>>> Foo = type("Foo",(),{'meth':meth1}) # make a class
>>> foo = Foo() # make an instance
>>> foo.meth() # call a method
i am meth1
