Sure, that was just an exampel of keyword re-use, you can do the exact same without scores :

out int foo()
{
    return  m_foo;
}
in int foo(int value)
{
    m_foo = foo;
}

Many variations possible on this theme ;) So not wanting a new keyword is not a show-stopper for solutions involving the use of keywords, in and out can be used there with no ambiguity i can think of (maybe others will though)
