#13305: static: check for identifiers should only consider term level variables -------------------------------------+------------------------------------- Reporter: edsko | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 Resolution: | Keywords: | StaticPointers 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 edsko):
I'm surprised that is accepted, and I am no longer sure of what the specification is, or how it is implemented. (E.g. if you wrote Num a instead of, or as well as, Typeable a it would not work.)
This is because the `Typeable` comes from `static` itself; we can have polymorphic static values (but they must be `Typeable`); we do not support adhoc polymorphism (and workaround this all the time using `Dict`s). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13305#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
