Comment:

 Doesn’t seem like it.
 http://www.haskell.org/ghc/docs/latest/html/users_guide/syntax-extns.html
 #pattern-synonyms mentions `pattern Foo` in export/import list, but does
 not say that proper constructors can also be addressed this way.

 I guess it should also be mentioned in
 http://www.haskell.org/ghc/docs/latest/html/users_guide/syntax-extns.html
 #explicit-namespaces

 Anywhere else where this should be mentioned?

 (Reopening as a task.)
