User's Guide 7.4.4 ExplicitTypeOperators typo
There is now some potential ambiguity in import and export lists; for example if you write import M( (+) ) do you mean the function (+) or the type constructor (+)? The default is the former, but with -XExplicitNamespaces (which is implied by -XExplicitTypeOperators) GHC allows you to specify the latter by preceding it with the keyword type, thus: [...]
GHC lists no extension -XExplicitTypeOperators, so it is assumed to be a mistake intended to be -XTypeOperators.
