#14112: bang patterns on pattern synonyms? (left vs right hand sides) -------------------------------------+------------------------------------- Reporter: carter | Owner: RyanGlScott Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler | Version: 8.2.1 Resolution: | Keywords: | PatternSynonyms 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 carter): so what i'm sensing is the point that normal / "strict" data types are only strict on construction, but lazy on matching (except perhaps when dealing with unpacked/unboxed style internal tricks eg mapping Int to Int# etc). In contrast, we have here a way that can express lazy construction and strict matching? am i missing something? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14112#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
