#12540: RFC: Allow not quantifying every top-level quantifiee -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #14245 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): This behavior of parentheses is awful, in my view. Redundant parentheses should never have any impact. (Yes, yes, I know: that statement is a tautology, as it's essentially the definition for "redundant". But I choose to define "redundant" to mean parentheses that are not needed to disambiguate / alter the precedence of operators.) In my opinion, this example shows why the current setup with scoped type variables is a small misdesign. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12540#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
