There are two patterns I find in my code that I'm still unhappy with but I don't know how to clean up.
The first is: (if (:attr obj) obj (assoc obj :attr something)) I'm basically saying, give this hash-map an attribute if it doesn't already have it. And just return the thing with an attribute, regardless if I had to add it or not. This version is ugly because it repeats obj three times. I could write my own macro to de-duplicate it, but I avoid doing that when I can because there's usually a better built-in solution that I just don't know about yet. The second is like it: (if (some-test obj) obj (some-transformation obj)) In this one, I just want to return the object, but maybe transform it first. But the reference to obj happens three times! Still feels like it could be cleaned up. Any thoughts on how to clean these up? -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
