#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 chshersh): Alternative naming option would be `NonEmptyFoldable` or `FoldableNE` or something similar. But this is either long or non-uniform. `Foldable1` is good enough. And we probably won't need type classes like `Eq1` and `Show1` in future since we have `QuantifiedConstraints` landed in GHC. In some moment of time they can be deprecated and removed. So we only need to prepare for StackOverflow and Reddit questions like ''Why `Eq1` and `Show1` are different from `Eq` and `Show` in not the same way as `Foldable1` from `Foldable`?''. But I guess this is manageable. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13573#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
