          Issue ID: 19217
           Summary: object.destroy doesn't handle non D interfaces
                    correctly
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: druntime

          Reporter: doob@me.com

The code for "object.destroy" for interfaces looks like:

void destroy(T)(T obj) if (is(T == interface))
{
    destroy(cast(Object)obj);
}

Casting an interface will only work for a D interface. There are C++, Objective-C and COM interfaces as well.
