Hi, This review is mainly based about the lambda part of FC++, as I've not had chance to have a proper look at the other parts (if I do before review period is over I'll add a 2nd review, but that is unlikely). I have no experience in Haskell or other functional programming languages. * What is your evaluation of the documentation? Seems fine and comprehensive. I think more motivating examples are required; it felt a bit abstract. * What is your evaluation of the potential usefulness of the library? I think Boost Lambda and FC++ lambda expressions are both about as ugly as each other, and the BLL versions seem to be a few characters shorter. So even if FC++ is accepted I will continue to use BLL. I am interested in the lazy-evaluation list, but cannot think of any code where I'd need it enough to justify the learning curve and the extra dependency. * Did you try to use the library? No. * How much effort did you put into your evaluation? About 2-3hrs reading docs and reading/writing mails. * Do you think the library should be accepted as a Boost library? No, simply as I personally have no need for it. Also it seems the more libraries in boost the longer it takes to get a regression-passing release out, so adding it just because it is clever and well-written is not a good enough reason in my opinion.
