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

 In [changeset:"d1eaeadb08c1412c1572124efaf341bdc0976ccb/ghc" d1eaead/ghc]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="d1eaeadb08c1412c1572124efaf341bdc0976ccb"
 Temporary fix to Trac #14380

 This fix replaces an utterly bogus error message with a decent one,
 rejecting a pattern synonym with a list pattern and rebindable syntax.

 Not hard to fix properly, but I'm going to wait for a willing volunteer
 and/or more user pressure.
