Comment (by Simon Peyton Jones ):

 In [changeset:"54e655536ecf7eba755b334058d5c22dab251bea/ghc"]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="54e655536ecf7eba755b334058d5c22dab251bea"
 Derive Typable for promoted data constructors (Trac #8950)

 I got sucked into a significant refactoring of the way that
 Typeable instances are derived.  This makes it simpler and
 more uniform.

 I also improved the documentation in the user manual.  Typeable
 really is different to other classes, and now gets its own subsection.
