Comment (by simonpj):

 Good suggestion.  I had a look, but it's really not convenient to do this.
 Haskell ''never'' allows a qualified name in a binding position, and it's
 the code that parses bindings that emits the error message.  Of course
 this'd be fixable by adding some more context information, but it looks
 like more than just adding a boolean flag to me.

 So I think other feature requests are probably higher priority.  But if
 you'd like to have a go yourself, the error comes from
 RdrHsSyn.checkFunBind.
