- PyIntObject represents a (long) integer. This is an immutable object;
- an integer cannot change its value after creation.
-
- There are functions to create new integer objects, to test an object
- for integer-ness, and to get the integer value. The latter functions
- returns -1 and sets errno to EBADF if the object is not an PyIntObject.
- None of the functions should be applied to nil objects.
-
- The type PyIntObject is (unfortunately) exposed here so we can declare
- _Py_TrueStruct and _Py_ZeroStruct below; don't use this.

- False and True are special intobjects used by Boolean expressions.
- All values of type Boolean must point to either of these; but in
- contexts where integers are required they are integers (valued 0 and 1).
- Hope these macros don't conflict with other people's.

- Don't forget to apply Py_INCREF() when returning True or False!!!
