It's useful to see the square-bracket-and-comma list notation in
Haskell as syntactic sugar because you don't need to worry about what
it means; you just need to know how to mentally translate it into
applications of cons and nil, and you already know what those means.
Indeed, Haskell compilers are based on that same principle.
