I often see this mentality towards dynamic languages where they are treated like good tools for quick-and-dirty job. No! They require more discipline than statically compiled languages. And you ignore good design principles in Python,Groovy,bash,etc. at your own peril. Especially when the tooling sucks which is the case for Groovy for example.

It was first described in a wonderful book by Chris Okasaki - Purely functional data structures. But Clojure uses a different implementation of the same idea for performance

In Clojure there is this thing called structural sharing. All data types are represented as maps (32 branching if I remember correctly) and common subtrees are shared
