#14776: Add equality rule for `eqString` -------------------------------------+------------------------------------- Reporter: mpickering | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Locally I sometimes have to define a rule {{{ {-# RULES "eqStringEQ" forall x . eqString x x = True #-} }}} in order for "stuck" expressions to evaluate to `True` and for a case expression to be eliminated. Is there is a reason not to include this RULE directly in GHC.Base? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14776 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
