Because ! is an operator, you need to enclose it in parentheses. Also, the (Map) in the import is already the list of things you are importing; you can just add to that. So do the following: Import these without qualification:

import Data.Map (Map, fromList, (!)) Import everything else (actually including Map, fromList and (!)) with qualification "Map": import qualified Data.Map as Map
