Hello all: I've decided I'm going to try to merge in stuff from my QTILITY library [1] in an attempt to reduce the number of utility libraries out there -- provided the stuff fits with the goals of Alexandria. Xach and I decided it's best not to add more utility libraries to Quicklisp. I've created a patch that adds MULF and DIVF, which do what you might expect (modify macros for * and /). I also added some numerical predicates that I myself like, as well as others: POSITIVEP, NEGATIVEP, NON-POSITIVE-P, NON-NEGATIVE-P, NON-ZERO-P. As you might notice, they sound especially familiar to those who read mathematics literature. Also, would it be possible for me to have push permissions? I hope you'll take these attached patches into consideration. Thanks, Robert Smith [1] https://bitbucket.org/tarballs_are_good/qtility/src
