Sometimes I find myself writing code like this: (defn magnify [n] (if (pos? n) (inc n) (dec n)))
...and I want to get rid of all those "n"s. I've looked for a macro like this, but couldn't find it, so I wrote it: https://gist.github.com/jamesmacaulay/4993062 Using that, I could re-write the above like this: (def magnify (iffn pos? inc dec)) I can imagine a condfn macro, too: (def magnify2 (condfn pos? inc neg? dec :else identity) Has this kind of conditional function composition been explored much? I couldn't find anything like it in the standard library, but maybe I wasn't looking hard enough.
