-- Functions for generic traversals across Futhark syntax trees.  The
-- motivation for this module came from dissatisfaction with rewriting
-- the same trivial tree recursions for every module.  A possible
-- alternative would be to use normal \"Scrap your
-- boilerplate\"-techniques, but these are rejected for two reasons:
--
--    * They are too slow.
--
--    * More importantly, they do not tell you whether you have missed
--      some cases.
--
-- Instead, this module defines various traversals of the Futhark syntax
-- tree.  The implementation is rather tedious, but the interface is
-- easy to use.
--
-- A traversal of the Futhark syntax tree is expressed as a record of
-- functions expressing the operations to be performed on the various
-- types of nodes.
--
-- The "Futhark.Transform.Rename" module is a simple example of how to
-- use this facility.
