--     One major note:
  --     driver.love gives you zero control over the order definitions are
  --     loaded in. To avoid issues, never initialize one global based on the
  --     value of another. Perform such initializations inside a function like
  --     on.initialize.

-- ONE MAJOR GOTCHA
-- You might be used to programming with files. I think this approach is
-- superior, but it has one major drawback: you can't make any assumptions
-- about the order definitions are loaded in. In particular, don't mention one
-- global in the initialization of another.
--
-- Foo = { Bar }
--
-- Things might work fine for a long time before breaking.
--
-- As a corollary, never use the environment to modify this buffer. `on`
-- should always live in version id 1.
--
-- There are no such restrictions on function definitions.
