#13593: Unexpected behavior from Data.List.groupBy -------------------------------------+------------------------------------- Reporter: dsf | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Core Libraries | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Documentation | Unknown/Multiple bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by dsf): Yes, the Haskell report does contain this specification. I'm just trying to improve the documentation which is typically used by someone who is in the process of building Haskell code and is perhaps somewhat removed (at that moment) from the design decisions discussed in the Haskell report. I have found that the requirements of the reference documentation used while writing code is very different from those of the documents defining the language. The name and signature of groupBy give the impression that what I tried to do above would work, so I'm assuming that my mistake and consequent loss of time might be one that others would also make. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13593#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
