Comment:

 These really do parse differently though: `(x)` is a pattern `x` enclosed
 in parentheses, while `(.)` is a single identifier (infix operator in
 prefix form).

 If you consult
 https://www.haskell.org/onlinereport/haskell2010/haskellch10.html I think
 you will find that these outputs match the parses specified by the Report.
 Please reopen if you disagree.
