struct Test {}

void takes( ref const Test x ) {}

Test gives() { return Test(); }

int main() {
    takes( Test() );     // compiles
    // takes( gives() ); // doesn't compile
    readln();

    return 0;
}

Is this required behaviour? The compiler complains about gives() not being an
lvalue, but the code doesn't seem to require it to be an lvalue.
