           Summary: Delegate Covariance
           Product: D
           Version: D2
          Platform: Other
        OS/Version: Windows
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: dsimcha yahoo.com



class A {}
class B : A {}

void main() {
    A delegate() foo;
    B delegate() bar;
    foo = bar;
}

Error: cannot implicitly convert expression (bar) of type B delegate() to A
delegate()

Is there any reason why this shouldn't work?
