John, in the $7.11 blog post why did you use the `amb-lazy` word instead of the `amb`, which seems to do the same thing (after reading the docs).

Thanks, I fixed that in my GitHub repo.By the way, if you want another puzzle to try solving maybe using backtracking, this one is fun:,On Mon, Mar 20, 2017 at 11:22 PM, CW Alston <cwalsto...@gmail.com> wrote:Hi -The intricacy of the code in backtracking.factor is pretty amazing; a good exampleof making use of the continuations vocab, for sure. The two examples on there-factor.blogspot:are a great help in figuring out how non-determinism via John McCarthy's amb(ambiguous) operator works in backtracking. Thanks for these!Note that the github code def for `digit` in send-more-money.factor is missing a word:: digit ( seq -- n )digits swap amb-lazy ;should read: digit ( seq -- n )digits swap diff amb-lazy ;and then all is well.Cheers,~cw--~ Memento Amori
