-- | Field access, inspired by the lens library. This is merely reverse
-- application, but allows us to write things like @(1, 2)^._1@ which is
-- likely to be familiar to most Haskell programmers out there. Note that
-- this is precisely equivalent to @_1 (1, 2)@, but perhaps it reads a little
-- nicer.
