-- Without exporting it here, a `hiding` clause there causes a compilation
-- error. But without hiding it there, the name conflicts with the one
-- imported from Agda.Syntax.Internal.
--
-- This is only a problem with ghci, which will load a fully-compiled module if
-- available; but that module will contain more symbols than just the few in
-- the .hs-boot
