#277 closed defect (fixed)

keywords should not be renamed by syntax expansion

Reported by: felix winkelmann Owned by: felix winkelmann
Priority: critical Milestone:
Component: expander Version: 4.5.x
Keywords: keywords Cc: sjamaan
Estimated difficulty:


(Example by sjamaan)

(define-syntax foo
  (syntax-rules ()
    ((foo procname)
     (define (procname #!key (who "world"))
       (print "hello, " who)))))

(foo bar)

(bar who: 1)

expands into:

(set! bar
    (let ((who3040
            (##sys#get-keyword 'who30: tmp3839 (##core#lambda () '"world"))))
      (let () (print '"hello, " who3040)))))

and doesn't detect the "who:" keyword correctly on invocation.
Note that the who variable must be renamed, the keyword not.
