`self` is not magical or a language keyword. It's just the
conventional name for the first argument to an instance method (which
is the instance the method is acting upon). For example, a small
minority use `s` instead for brevity. There is no variable `self` in
the parameters of __new__(), hence you get a NameError, as you would
when trying to access any other nonexistent variable.
Also, you shouldn't use `class_ ` as the name of the first argument to
__new__(). Use `cls` instead since that's the conventional name for
it.
My best guess as to what you're trying to do is (completely untested):
class myclass(long):
def __new__(cls, init_val, reg_info):
print reg_info.message
instance = long.__new__(cls, init_val)
instance.reg_info = reg_info
return instance
