Yes, it doesn't do anything yet (apart from update a currently discarded
accumulator (symbol table)).

It brings tears to my eyes to see such a beautiful function ;) You've hit the nail on the head Ryan. The new version of my second previous code snippet now no longer requires "fixpu*", and is:
typeCheckAST (Program pus) = Program $ snd $ mapAccumL f [] pus
where f st pu = (st ++ [("",[])],pu)
I'm confused about this. If I'm reading this correctly, snd $ mapAccumL f (undefined) pus == map id pus == pus -- ryan
