void test1(ref bool val = true) {
}

void test2(out bool val = true) {
}

void main()
{
    bool x;
    test1(x);  // compiles ok
    test2(x);  // compiles ok

    test1();  // Error: constant true is not an lvalue
    test2();  // Error: constant true is not an lvalue
}

The compiler should probably disallow that kind of function signature
regardless of any calls. The initializer doesn't really do anything.
