This has a fancy name: The Reader Monad. Don't be scared though! Essentially it's a way of composing functions together, like a(b(c(d(...)))), but it 'skips' the first argument of every function, leaving a 'hole'. We get back a function which plugs its argument into all of these holes, ie. dependency injection!
