What's worrying is that func2() ends up being called:

-----
interface I1 { void func1(); }
interface I2 { void func2(); }

interface I3 : I1 { }
interface I4 : I2, I3 { }

import std.stdio;

class Test : I4
{
    void func1() { check = true; }
    void func2() { assert(0); }
    bool check;
}

void main()
{
    I4 sub = new Test;
    sub.func1();  // triggers assertion (func2 called)
}
