Comment(by zbigniew):

 Ref impl is obviously wrong and the bug was propagated to Chicken.  It
 uses string-compare's PROC= branch and returns its value and, as string-
 compare states, "in the case of PROC=, it is always END1" -- not a
 boolean.  Changing "values" to (lambda (i) (and i)) should fix it.

 Question is, who is right--the guy that wrote the srfi, or the guy that
 wrote the reference implementation.

 The answer is they are both right.  Please, put down the Sig Sauer, I beg
 you.
