#15211: exprFreeVars does not include type variables -------------------------------------+------------------------------------- Reporter: goldfire | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.3 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: -------------------------------------+------------------------------------- The `exprFreeVars` function returns the free variables of an expression. However, this function doesn't include the type variables free in the free term variables. This might be OK for some uses, but it seems ''not'' OK if we use the result of `exprFreeVars` in an `InScopeSet`, which is done in many places. I don't have a program that exhibits misbehavior, but I feel fairly sure that we have a problem here. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15211 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
