Should be more liberal parsing pattern synonyms with view patterns
Redundant parentheses are required around a view pattern if it is used on the RHS of a pattern synonym definition. I think that parsing should be relaxed to allow the first definition.
-- Fails to parse, bug?
pattern IsTrue :: Show a => a
pattern IsTrue <- (== "True") . show -> True
-- Parses
pattern IsTrue :: Show a => a
pattern IsTrue <- ((== "True") . show -> True)Trac metadata
