Potential bug in __traits(parent).

[Mike]

Consider the following code:

/*********** mmio.d ************/
module mmio;
mixin template HasValue(uint value) {
    static uint getValue() {
        return value;
    }
}

mixin template Parent() {
    final abstract class Child(uint value) {
        mixin HasValue!(value);
    }
}

/*********** test.d ************/
module test;
import mmio;

mixin Parent;

alias Two = Child!(2);

/*********** main.d ************/
import std.stdio;
import test;

void main()
{
    writeln(__traits(parent, test.Two).stringof);
    writeln(__traits(parent, __traits(parent, 
test.Two)).stringof);

    readln();
}

DMD 2.065 Output:
Child!(2)
Child!(2)

GDC 4.8.2 20130725 Output:
Child
Child

LDC 0.12.1 Output:
Child
Chlld

All of these seem wrong to me.  What I expect for output is:
module test
{the second `writeln` shouldn't compile since `test` has no 
parent}

A couple of observations:
1. `Child` is not the parent of `test.Two`, `test` is the parent 
of `test.Two`.
2. If you believe `__traits(parent, test.Two)` is `Child`, 
`Child` should not be its own parent.

Incidentally, if I remove the template parameter on `Child`, I 
get the results I expect.

Could someone please confirm if this is a bug or not?

Thanks for the help,
Mike
