-/* Three Bit Tags
-
- * 000 -- a non-immediate value. Points into the pair heap.
- *
- * 001 -- a gloc (i.e., a resolved global variable in a CAR in a code graph)
- * or the CAR of an object handle (i.e., the tagged pointer to the
- * vtable part of a user-defined object).
- *
- * If X has this tag, the value at CDAR(X - 1) distinguishes
- * glocs from object handles. The distinction only needs
- * to be made in a few places. Only a few parts of the code know
- * about glocs. In most cases, when a value in the CAR of a pair
- * has the tag 001, it means that the pair is an object handle.
- *
- * 010 -- the tag for immediate, exact integers.
- *
- * 011 -- in the CAR of a pair, this tag indicates that the pair is a closure.
- * The remaining bits of the CAR are a pointer into the pair heap
- * to the code graph for the closure.
- *
- * 1xy -- an extension tag which means that there is a five or six bit
- * tag to the left of the low three bits. See the nice diagrams
- * in ../doc/code.doc if you want to know what the bits mean.
