Node Version Manager (https://github.com/nvm-sh/nvm) works perfectly across native node installations as well as emulated Rosetta installations. The trick I am using here is to install one LTS version of node under Rosetta and another stable version as native binary.

Well I have a working Aporia version on my Yosemite OS X 10.10.2 from the new-suggest branch of the repository.
BUT the lengths I had to go to get this working are plastered with stuff I did not understand :)
Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.
