Changes (by simonpj):

  * milestone:  6.8 branch => 6.10 branch

Comment:

 * We aren't sure if the "NB: it's monomorphic" note has been added; it
 should be.
  * The warning would be more informative if it was postponed until the end
 of typechecking, because then the 't' would be filled in.

 It'd be v useful if you could attach a concrete example.  Then we might
 actually fix this one.  Thanks

 Simon
