Ha, the argument order as written here was just off the top of my head; when I look at where I actually use it, it's [test f value] like Sean said, for use with partial. That said, I like to-fix's brevity over using partial all the time. Clojure makes it so easy to compose functions on the fly tha

meantime, take useful for a spin, and see if the enhanced versions of pipe are of any use to you. If nothing else, I recommend you change the argument order to your pipe function: (defn pipe [value test f]) is clearly the "correct" signature, since it means that (like fix) you can

2011-10-14 Thread Daniel Bell
One higher-order function I've found useful as I've goofed around with clojure has been one that I made up myself, but it's proved so useful and so simple that I have to believe it's in core somewhere: (defn pipe [test value f] (if (test value) (f value) value)) Is this a core f
