For anyone designing a programming language, enforce namespace to includes/imports! and if possible, don't allow top level side effects.
let foo = include "lib/foo.hurl"
foo.init()
it's much easier to reason about then, for example:
include "lib/foo.hurl" // side effects
baz(buz) // function and variable that I have no idea if they are in the standard library, or included *somewhere*
