Comment (by archblob):

 In fixing {{{:kind}}} we just have to also tidy the type because currently
 it's not for some reason. I could patch that by setting {{{-fprint-
 explicit-foralls}}}, {{{-fprint-expicit-kinds}}} and printing thorough
 {{{pprTypeForUser}}} but I remember that you mentioned something about
 removing tidying from {{{pprTypeForUser}}} so I would like some input on
 this.
