Understood.

I don't have a strong opinion as to which class should be returned. I
just don't find the results always intuitive. Is there a rationale for
the fact that:

    (x * 2).class # => Sub
    # but...
    (x+x).class # => Array

Or similarly, why does:

    (x.slice(0,0)).class # => Sub
    # while...
    (x.slice!(0,0)).class # => Array

Thanks
