D2 changes! Removed druntime from the repository again.. Sorry :/ Updated the druntime port a bit, now requires druntime from trunk. Added info in runtime/README on how to get druntime from trunk. Added patch to add LDC support to druntime. Removed some debug logging from D2 builds. Fixed broken typeinfo for const/invariant in D2.

interface Iin
{
    void[] read(size_t n);
}

interface Iout
{
    size_t write(void[] d);
}

class C : Iin
{
    void[] read(size_t n)
    {
        return null;
    }

    size_t write(void[] d)
    {
        return 0;
    }
}

void main()
{
    scope c = new C;
}
