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

 In [changeset:"395ec414ff21bc37439194bb31a8f764b38b0fca/ghc"

 {{{
 #!CommitTicketReference repository="ghc"
 revision="395ec414ff21bc37439194bb31a8f764b38b0fca"
 Allow implicit parameters in constraint synonyms

 This fixes Trac #11466.

 It went bad by accident in
  commit ffc21506894c7887d3620423aaf86bc6113a1071
  Refactor tuple constraints
 }}}
