+-- | Mapping of prelude functions to vectorised versions.
+-- Functions like filterP currently have a working but naive version in GHC.PArr
+-- During vectorisation we replace these by calls to filterPA, which are
+-- defined in dph-common Data.Array.Parallel.Lifted.Combinators
+--
+-- As renamer only sees the GHC.PArr functions, if you want to add a new function
+-- to the vectoriser there has to be a definition for it in GHC.PArr, even though
+-- it will never be used at runtime.
