;;;; binding and unbinding
;;; BIND -- Establish VAL as a binding for SYMBOL. Save the old value and
;;; the symbol on the binding stack and stuff the new value into the
;;; symbol.
;;; See the "Chapter 9: Specials" of the SBCL Internals Manual.
;;
;;; FIXME: Split into DYNBIND and BIND: DYNBIND needs to ensure
;;; TLS-INDEX, whereas BIND should assume it is already in place. Make
;;; LET &co compile into BIND, and PROGV into DYNBIND, plus ensure
;;; TLS-INDEX at compile-time, and make loader and dumper preserve
;;; the existence of a TLS-INDEX.
