#11432: Cannot export operator newtype -------------------------------------+------------------------------------- Reporter: phadej | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 8.0.1-rc1 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 goldfire): There's not going to be an easy solution to this. The problem is that we only know that `(-.->)` is a type when we see the open parenthesis after it. But the parser has only one-token lookahead. I would actually say that the current behavior -- requiring `type` -- is correct. We then have a rule that's simple for both parsers and people: any symbol not beginning with a `:` is assumed to be a variable, not a type. Note that we don't need to worry about standards-compliance here, as `TypeOperators` is not standardized. If it doesn't already, `TypeOperators` should imply `ExplicitNamespaces`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11432#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
