Comment (by carter):

 after speaking with alanz on IRC a smidge, he's meaning "CPP as a support
 tool for portable code across platforms/configurations ghc versions", vs
 #define'd names/procedures as a poor mans macrosystem that lighter weight
 than TH and simpler to use/write

 this ticket is about the former, though its definitely true we would
 benefit from thinking about a decent macro systemy thing for syntactic
 abstraction
