#10971: ExtendedDefaultRules defaults to [] for Foldable/Traversable -------------------------------------+------------------------------------- Reporter: kanetw | Owner: kanetw Type: feature request | Status: patch Priority: normal | Milestone: 8.0.1 Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #10963 | Differential Rev(s): phab:D1329 Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): I find it a little counterintuitive to have one defaulting list have types of several different kinds in it. For example, `default (), []` is accepted, and has the exact same meaning as `default [], ()`. I'd much prefer separating these out. But I won't make a big deal of it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10971#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
