+ ;; FIXME:
+ ;; * We should ensure the existence of TLS index for LET-bound specials
+ ;; at compile/load time, and use write a FAST-BIND for use with those.
+ ;; * PROGV will need to do this, but even there this should not be inline.
+ ;; This is probably best moved to C, since dynbind.c also needs to do this.
