It can be implemented in a backwards-compatible way as a subtype of a Tuple.

struct FindSplit(R)

    Tuple!(R, "pre", R, "separator", R, "post") asTuple;

    bool opCast(T : bool)()
    {
        return !asTuple.separator.empty;
    }

    alias asTuple this;
}

Tuple!(R, "pre", R, "separator", R, "post") is a subtype of Tuple!(R, R, R), which should be the current return type.

Nice! Should I make a PR?
