-- Every identifier below is imported directly from the module it's
-- actually declared in, rather than from an intermediate re-export
-- module. Haddock has a bug where docs of an identifier re-exported
-- through more than one hop (declaration site -> intermediate re-export
-- -> here) silently render blank on Hackage; importing straight from the
-- declaration site keeps this a single hop.
