I'm done with this for now, but I'll definitely have to reopen it once we figure out what's going to work.

Couple issues I noticed.

You're doing:

any (unwrapToken (lookAheadToken parsingData) ==) ("MP_PLUS", "MP_MINUS", "MP_NOT", "MP_LPAREN")

when you should be doing:

any (unwrapToken (lookAheadToken parsingData) `elem`) ["MP_PLUS", "MP_MINUS", "MP_NOT", "MP_LPAREN"]

or something similar. I haven't tested to see if that will work, but your current method is trying to match a String with a Tuple.

You have:

getTokenType (lookAheadToken parsingData) ==  "IdentifierOrLiteral"

but on the next line you're doing:

getTokenType lookAheadToken parsingData ==  "ReservedWord"

and this will fail, because the program will interpret getTokenType as a higher-ordered function and fail, because it isn't.

Awesome! Thanks
