Comment (by Simon Peyton Jones <simonpj@…>):

 In [changeset:"022f8750edf6f413fba31293435dcc62600eab77/ghc"]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="022f8750edf6f413fba31293435dcc62600eab77"
 Refactoring around TyCon.isSynTyCon

 * Document isSynTyCon better
 * Add isTypeSyonymTyCon for regular H98 type synonyms
 * Use isTypeSynonymTyCon rather than isSynTyCon where
   the former is really intended

 All arose as part of a bug I introduced when fixing Trac #9102,
 thinking that isSynTyCon meant H98 type syononyms.
