;; with-fluids is a convenience wrapper for the builtin procedure
;; `with-fluids*'. The syntax is just like `let':
;;
;; (with-fluids ((fluid val)
;; ...)
;; body)
(defmacro with-fluids (bindings . body)
(let ((fluids (map car bindings))
(values (map cadr bindings)))
(if (and (= (length fluids) 1) (= (length values) 1))
`(with-fluid* ,(car fluids) ,(car values) (lambda () ,@body))
`(with-fluids* (list ,@fluids) (list ,@values)
(lambda () ,@body)))))
