I’m curious why you’re using `with_indifferent_access` here instead of just using self?
Since with_indifferent_access is a Rails extension to the core Hash library, this would make this a a Rails Hash#contain?(other) implementation instead of a Ruby one. 🙂
True true, was using it for a rails project, perfectly fine without the indifferent 🙂
