I tend to agree, I think. I certainly can't think of a syntax that would make me happy. It just feels like a bit of a smell that I keep using ->> to process sequences in similar ways.
The data.zip "xml->" macro is an example of something like what I'm thinking about - it lets you process sequences of xml data nicely: http://clojure.github.io/data.zip/#clojure.data.zip.xml/xml-> ... but I can't see a way to use something similar for the sort of data I'm processing. I'll let this percolate, and stick to just using lots of (map) and (filter) instead. - Korny On 6 February 2014 18:34, Jozef Wagner <jozef.wag...@gmail.com> wrote: > I agree with Colin, the cognitive load is greater than benefits of such > approach.
