          Issue ID: 19557
           Summary: extern(C++, ns) and extern(C++, class) interact weird
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: turkeyman@gmail.com

This error:

  extern(C++, "ns")
  extern(C++, class)
  struct test {}

  > Error: redundant linkage `extern (C++)`

But this works:

  extern(C++, class)
  extern(C++, "ns")
  struct test {}

No problem!
