Thanks! Definitely still need to brush up my FP (only dabbled in Clojure, LISP and Scala a bit before) which is why Elixir is so great to pick up and learn as I can expand my mind on FP, distributed systems/OTP and many other great concepts.
To my shame, before I mistook “Y combinator” for the general “we derive the whole of computation from just functions” which I think is rather called lambda calculus 
A bit OT, but if you have some good resource to share (book or web) for learning about “ALL THE COMBINATORS” I’d appreciate it. Maybe I should dig out Land of LISP again…
