Specter – Manipulating nested data structures in Clojure

PSA: Nathan will be doing a talk about Specter at the next SF Clojure Meetup http://www.meetup.com/The-Bay-Area-Clojure-User-Group/events...

I could make good use of this kind of library in ClojureScript. Sometimes you need more than update-in, but less than DataScript.

This library is really useful, especially in updating sets of nested data.
