Hello.
Why does it return -1? Could anyone explain?
(Comments are mine.)
(call-with-values (lambda () (values 4 5))
(lambda (a b) b)) ; a is 4 and b is 5; return 5
⇒ 5
(call-with-values * -)
⇒ -1
More:
(call-with-values + +)
0
(call-with-values + -)
0
(call-with-values - -)
ERROR: Wrong number of arguments to -
ABORT: (wrong-number-of-args)
