          Issue ID: 19972
           Summary: no shadowing error for nested functions
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1

float x;
void test()
{
    short x;
    void nested() const
    {
        int x;
        pragma(msg, typeof(.x)); // float - fine disambiguated with leading .
        pragma(msg, typeof( x)); // int - ?? should give error
    }
}


this should give an error that the int x shadows the short x
