Comment (by simonpj):

 I think this ticket is now done (as part of the "wildcard refactor" patch
 (1e041b7382b6aa329e4ad9625439f811e0f27232), except that we should remove
 `-fwarn-context-quantification` altogether (according to comment:20), or
 deprecate it.   It already does nothing.

 Ben: could you do this, and close?

 Simon
