           Summary: derived nested classes in derived outer class.
           Product: D
           Version: 1.035
          Platform: PC
        OS/Version: Linux

This should compile but does not.

class A {
    class I1{
    }
}

class B : A {
    class I2 : I1 { // line 9
    }

    I1 getI(){
        return new I2;
    }
}
void main(){}

test.d(9): class test.B.I2 is nested within B, but super class I1 is nested
within A

Are you *sure* this should compile or do you *want* it to compile?
There's a difference ;)  I believe back in 0.126 when nested classes
were implemented, I suggested this to Walter and the official response
was "AIIIIIIEEEEEE", or something like that.  Translation: probably
too much trouble to be worth it?

In real live Java code i found this constellation while porting it.
Sure, i found a workaround, but that is not nice.
