The reference manual for guile 2.0.11 has an error in Section 7.6.2.5 on rnrs lists. The statement "identical to the fold ..." is not quite correct. The section says:
fold-left combine nil list1 list2 . . . [Scheme Procedure] fold-right combine nil list1 list2 . . . [Scheme Procedure] These procedures are identical to the fold and fold-right procedures provided by SRFI-1. See Section 7.5.3.5 [SRFI-1 Fold and Map], page 556, for documentation. In section 7.5.3.5, the manual says: (fold cons ’() ’(1 2 3)) [...] (3 2 1) But, fold-left does not work like fold: the arguments to the procedure to fold-left are reversed with respect to fold:. guile i2.0.11correctly gives the following: (fold-left cons '() '(1 2 3)) => (((() . 1) . 2) . 3) (fold-left xcons '() '(1 2 3)) => (3 2 1) Matt
