Comment (by simonpj):
You'd refer to `GHC.Base.map` or whereever `map` is actually defined.
The problem you are trying to solve is this: you want Derive to print out
a Haskell program that mentions `map` and, when compiled, will get the
right `map`. The only way I know to do that for sure is
a) print out `GHC.Base.map` and import `GHC.Base` (or whatever the right
module is; Dervive, being a TH program, can find out easily.
b) or add some new lexical syntax so you can `{-# ORIG #-} GHC.Base.map`
as I suggested earlier.
The advantage of (a) is that can do it right away, without waiting for
some not-yet-designed feature to be implemented.
