Changes (by simonmar):

  * status:  new => closed
  * resolution:  => wontfix


Comment:

 You are right, but it's not likely we'll do anything about this.  GHC's
 parser is generated by Happy, and in general it's not possible to give
 more informative parse error messages without more support from Happy
 itself.
