Suggest PatternSynonyms
If I try to compile a pattern type signature like
pattern P :: G Intwithout having enabled PatternSynonyms then I get the error
Pat.hs:8:1:
Invalid type signature: pattern P :: G Int
Should be of form <variable> :: <type>We could easily work out to suggest that the user enable PatternSynonyms here.
