#13573: Add Foldable1 to base -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: (none) Type: feature request | 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: #10365 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by andrewthad): The name of the typeclass is a little unfortunate since the similarly named `Eq1`, `Show1`, etc. use the same suffix but with a very different meaning. Also, it's a little unfortunate that `Foldable1` doesn't have `foldl1`, `foldr1`, etc. Although there are already functions of the same name in `Foldable`, and there's no burning need to remove them any time soon, it would be nice to have a long-term plan to deprecate and remove them since they are a wart in the typeclass design. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13573#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
