44,Type signatures lose parentheses,anonymous,,"Under certain circumstances syntactically necessary parentheses are dropped from type signatures. Both of these examples are real code, though simpler examples could be found.


* Case 1: Strict multi-token fields

`data (f :+: g) e = Inl !(f e) | Inr !(g e)`


* Case 2: Per-argument comments on function arguments.

`pairWithBy :: (a -> b -> c)          -- ^ @(,)@ tuple homomorphism`
`           -> (c -> d -> d)          -- ^ @(:)@ list  homomorphism, pt. 1`
`           -> d                      -- ^ @[]@  list  homomorphism, pt. 2`
`           -> [a] -> [b] -> Maybe d  -- a safer @zip@ function`
