;;; (pages 528-529 of this second edition). It then optionally
;;; applies a code simplifier.
;;; If the value of *BQ-SIMPLIFY* is non-NIL, then BACKQUOTE

;;;
;;; (1) BQ-PROCESS applies the rules to remove occurrences of
;;; #:COMMA, #:COMMA-ATSIGN, and #:COMMA-DOT corresponding to
;;; this level of BACKQUOTE. (It also causes embedded calls to
;;; BACKQUOTE to be expanded so that nesting is properly handled.)
;;; Code is produced that is expressed in terms of functions
;;; #:BQ-LIST, #:BQ-APPEND, and #:BQ-CLOBBERABLE. This is done
;;; so that the simplifier will simplify only list construction
;;; functions actually generated by BACKQUOTE and will not involve
;;; any user code in the simplification. #:BQ-LIST means LIST,
;;; #:BQ-APPEND means APPEND, and #:BQ-CLOBBERABLE means IDENTITY
;;; but indicates places where "%." was used and where NCONC may
;;; therefore be introduced by the simplifier for efficiency.
;;;
;;; (2) BQ-SIMPLIFY, if used, rewrites the code produced by
;;; BQ-PROCESS to produce equivalent but faster code. The
;;; additional functions #:BQ-LIST* and #:BQ-NCONC may be
;;; introduced into the code.
;;;
;;; (3) BQ-REMOVE-TOKENS goes through the code and replaces
;;; #:BQ-LIST with LIST, #:BQ-APPEND with APPEND, and so on.
;;; #:BQ-CLOBBERABLE is simply eliminated (a call to it being
;;; replaced by its argument). #:BQ-LIST* is replaced by either
;;; LIST* or CONS (the latter is used in the two-argument case,
;;; purely to make the resulting code a tad more readable).

;;; Plain Javascript objects are the natural way to implement Common
;;; Lisp hash tables. However, there is a big differences between
;;; them which we need to work around. Javascript objects require the
;;; keys to be strings. To solve that, we map Lisp objects to strings
;;; such that "equivalent" values map to the same string, regarding
;;; the equality predicate used (one of `eq', `eql', `equal' and
;;; `equalp').
;;;
;;; Additionally, we want to iterate across the hash table
;;; key-values. So we use a cons (key . value)
;;; as value in the Javascript object. It implicitly gives the
;;; inverse mapping of strings to our objects.
;;; If a hash table has `eq' as test, we need to generate unique
;;; strings for each Lisp object. To do this, we tag the objects with
;;; a `$$jscl_id' property. As a special case, numbers do not need to
;;; be tagged, as they can be used to index Javascript objects.
