#11815: Data.List: Add a function to get consecutive elements (mapConsecutives) -------------------------------------+------------------------------------- Reporter: holmisen | Owner: Type: feature request | Status: new Priority: low | Milestone: Component: libraries/base | Version: Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by nomeata): * cc: dfeuer (added) Comment: If we indeed provide this function here, we might as well want to invest the effort to provide a well-engineered implementation. You could try to find out if * an explicit recursion function is significantly faster and * if it is possible to write `zipConsecutive` as a good consumer or good producer or both, in terms of list fusion. David Feuer might be interested in thinking about the second point. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11815#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
