Dear Boost, The review period for CallableTraits is about to conclude (in about one hour, PST). So far, I have counted 5 formal reviews, alongside with other valuable feedback. All 5 formal reviews recommend acceptance (along with improvement suggestions, but I read none of them as being conditional). I will weight the different comments received through formal and informal reviews and come back with a decision regarding CallableTrait's inclusion in Boost by the end of next week. Thanks for everyone's involvement in the review. Louis P.S.: If you have a late review, submit it ASAP and I will consider it!
