#15263: Fuse zipWith3 -------------------------------------+------------------------------------- Reporter: goldfire | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 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: | -------------------------------------+------------------------------------- Comment (by goldfire): I noticed that `zipWith` itself has an explicit recursive definition, even though the rule right below it universally applies and zaps it to a `build` expression. I do not know the implications of these different implementation choices. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15263#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
