Comment:

 Replying to [comment:6 crockeea]:
 > The ticket as reported is really just about when the kind-roles should
 be printed, as that's the part I found confusing.

 In that case, this ticket is fixed. The `T16030` test case provides a
 regression test for this, as it displays:

 {{{#!hs
 type role Foo1 phantom
 }}}

 When `-fprint-explicit-kinds` is disabled, and displays:

 {{{#!hs
 type role Foo1 nominal phantom
 }}}

 When `-fprint-explicit-kinds` is enabled.
