Comment:

 Thanks for the report.  Happily this too is fixed as part of my work on
 wildcards.  Now for `Fails` you get
 {{{
 T11192.hs:7:14: warning:
     • Found type wildcard ‘_’ standing for ‘Int -> t -> t’
       Where: ‘t’ is a rigid type variable bound by
                the inferred type of go :: Int -> t -> t at T11192.hs:8:8
 }}}
 which is what you wanted.

 Simon
