+intobject 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 intobject.
+None of the functions should be applied to nil objects.
+
+The type intobject is (unfortunately) exposed bere so we can declare
+TrueObject and FalseObject below; don't use this.
