Comment(by parcs):

 I can think of two solutions:

 1) Mark `Pretty.text` as `NOINLINE` to ensure that the "text/str" rule has
 a chance to fire and that `Pretty.text` doesn't get inlined into the
 unfolding of `Outputable.text`. This solution has the caveat that
 `Pretty.text` can no longer get inlined.

 2) Add a corresponding "text/str" rule on `Outputable.text` and mark both
 `Pretty.text` and `Outputable.text` as `NOINLINE [0]` (to ensure that the
 rules get a chance to fire).
