Ok, so I took the rule rewriting idea and added a preprocessor instead, that
inserts 'assert's for you, currently just for head,tail and fromJust.
This program, for example:
module Main where
import qualified Data.Map as M
import Data.Maybe
main = do print f
f = let m =

So all this talk of locating head [] and fromJust failures got me
thinking:
Couldn't we just use rewrite rules to rewrite *transparently*
all uses of fromJust to safeFromJust, tagging the call site
with a location?
To work this requires a few things to go right:
