  Priority:  major    |   Milestone:                     
 Component:  hugs     |     Version:  200609             
Resolution:  invalid  |    Keywords:  instance extensions
----------------------+-----------------------------------------------------
Changes (by ross):

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

Comment:

 There's an error in the example: should be (a,a) in the instance.  If
 test1 is supplied with a signature, hugs then accepts this (but GHC 6.10
 doesn't).
