I'm uncomfortable with adopting an implementation when I don't know the spec, except by reading this entire ticket, which isn't really a good thing. Thanks!

[GHC] #8092: Map.unionWithMaybe

#8092: Map.unionWithMaybe -------------------------------------------+------------------------------- Reporter: sjcjoosten | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 7.6.3 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Easy (less than 1 hour) | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: -------------------------------------------+------------------------------- for Data.Map, I needed a "unionWithMaybe" function for my sparse system of linear equations (unionWithMaybe :: Ord k => (a -> a -> Maybe a) -> Map k a -> Map k a -> Map k a). My usage: (.+.) = Map.unionWithMaybe (\a b->case a+b of {0->Nothing;s->Just s}) (I do not think Map.unionWithMaybe can be expressed in terms of other functions without loosing performance, so I recon it would be a nice addition to the library.) I built this function myself by modifying the Data.Map implementation, but it would be nice to see it in the official version of Data.Map. Here is the file including the modifications I made to it. Feel free to use it, I will agree to whatever license you need to make it public. (PS: this is the first time I return modified source code to the maintainer, feel free to instruct me on how to do this in the future.) -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8092> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#4879: Deprecate exports -------------------------------------+------------------------------------ Reporter: basvandijk | Owner: Type: feature request | Status: new Priority: high | Milestone: 7.8.1 Component: Compiler | Version: 7.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by igloo): I've added the beginnings of a patch for this. It needs some polishing, but basically works. In essence, warnings are parsed in export lists, and kept in `AvailInfo` and then `Provenance`. When giving deprecation warnings, we check to see whether any provenance is warning-free, and if not then we print all the warnings. I think we probably want to parameterise `AvailInfo`; in particular, rather than {{{ addAvailInfoWarnings :: Map Name WarningTxt -> [AvailInfo] -> [AvailInfo] }}} we should have {{{ addAvailInfoWarnings :: Map Name WarningTxt -> [AvailInfo Name] -> [AvailInfo NameWarn] }}} `bestImport` in `extendImportMap` should probably be trying to find an import without a warning, too. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/4879#comment:12> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
