Pretty prints a pattern synonym type signature

pprPatSynType :: PatSynType -> Doc #

Pretty prints a pattern synonym's type; follows the usual conventions to print a pattern synonym type compactly, yet unambiguously. See the note on `PatSynType` and the section on pattern synonyms in the GHC user's guide for more information.
