Comment (by mpickering):

 Richard is right that I removed it because I thought there was some worry
 that the typechecker would have to get involved but if he says not then I
 think it's a good idea.

 I'm of the opinion that without this, pattern synonyms are a bit useless
 but apart from the two requests from Thomas and Eric I don't think wider
 opinion has been solicited. I'll clean up the wiki page and post it to
 ghc-devs.
