 The Release notes for version 7.6.1 says
 http://www.haskell.org/ghc/docs/7.6.1/html/users_guide/release-7-6-1.html
   The behavior of the TypeOperator extension has changed: previously, only
 type operators starting with ":" were considered type constructors, and
 other operators were treated as type variables. Now type operators are
 always constructors.
 But this change isn't reflected in the User's Guide.
   http://www.haskell.org/ghc/docs/7.6.1/html/users_guide/data-type-
 extensions.html
   http://www.haskell.org/ghc/docs/7.6.2/html/users_guide/data-type-
 extensions.html
   http://www.haskell.org/ghc/docs/7.6.3/html/users_guide/data-type-
 extensions.html
   A type variable can be an (unqualified) operator e.g. +. The lexical
 syntax is the same as that for variable operators, excluding "(.)", "(!)",
 and "(*)". In a binding position, the operator must be parenthesised. For
 example: ...
 I think this paragraph should be removed.
