pprFamInstLHS drops parentheses
If I say
data family (a + b) c d
data instance (Int + Bool) Double = FloatGHC says
• Expecting one more argument to ‘Int + Bool Double’
Expected a type, but ‘Int + Bool Double’ has kind ‘* -> *’
• In the data instance declaration for ‘+’Note the missing parens in the first line of the error.
Will fix shortly.
