I think the fact that procedure-source returns a "wrong type error"
if passed a procedure-with-setter is less than ideal:
guile> (version)
"1.6.2" ; happens in 1.7.0 as well
guile> (define test-func
(make-procedure-with-setter
(lambda (val) #f)
(lambda (val new-val) #f)))
guile> (if (procedure? test-func) (display (procedure-source test-func)))
standard input:7:37: In procedure procedure-source in expression
(procedure-source test-func):
standard input:7:37: Wrong type argument in position 1: #<procedure-with-setter>
ABORT: (wrong-type-arg)
Type "(backtrace)" to get more information or "(debug)" to enter the debugger.
So one's first reaction is that procedure? says it is a procedure,
then procedure-source says no it isn't; perhaps it could return #f
instead (as if does with an argument like abs or a foreign function)?
- procedure-source of procedure-with-setter,
