[throwamon]

This is the one question for which I still haven't understood the answers. But not just because Clojure is dynamically typed, and more because of its concept of "it's just maps". More specifically, how do you know for sure that a map that holds "everything" and has been passed around hundreds of functions will have the field you want with the shape you want at a certain point? Even with specs, how do you even reason about that?
