          Issue ID: 14410
           Summary: core.demangle doesn't handle typeof(null) correctly
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: druntime
          Assignee: nobody@puremagic.com
          Reporter: sludwig@outerproduct.org

The following code fails because demangleType("n") outputs an empty string
instead of "typeof(null)".

---
import core.demangle;

void main()
{
  assert(demangleType("n") == "typeof(null)");
}
