Uh, sorry I'm tired.

I see that now:

No: a workaround would be:

private int dummy1, dummy2;
void foo(out int x = dummy1, out int y = dummy2, out int z = dummy3){...}

int foo(out C x)
{
    return foo(x);
}

It complicates library code just a little but simplifies users code.

I thought the topic was initialization of out parameters.
