#13959: substTyVar's definition is highly dubious -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3732 Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Who arranges for the members of the in-scope set to have substituted kinds? It's not uncommon to start a substitution with some in-scope set (derived from a call to `tyCoVarsOfTypes` or similar) and then build it from there. No one touches the in-scope set. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13959#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
