#15220: ScopedTypeVariables binds a non-existent variable -------------------------------------+------------------------------------- Reporter: goldfire | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.5 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 simonpj):
But I still think it would be very strange if zonkTcTypeToType ever zonked a SigTv to Any.
I don't understand the question. In the example, `b` will not stand for a `SigTv` any more -- it'll stand for a `TauTv`, which can get unified with anything. I suppose we'll have to look at any remaining uses of `SigTv`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15220#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
