Hi,
If you are using the trunk (not 2.1.0), then you can compare any two
numerical types (but adding them is not currently allowed, but should be
allowed soon. follow: http://jira.codehaus.org/browse/XTENLANG-2075)
public struct Int implements Comparable[Int] /*TODO implements
Arithmetic[Int], Bitwise[Int], Ordered[Int]*/ {
class Test {
def compare[T](x:T,y:T) { T <: Comparable[T] } = x.compareTo(y);
def add[T](x:T,y:T) { T <: Arithmetic[T] } = x+y;
def test() {
var x:Int=2, y:Int=3;
use(compare(x,y)); // ok
use(add(x,y)); // cause an ERROR because Int still doesn't
implement Arithmetic
}
}

What happens now with your Lotus Notes apps - do you make another costly
upgrade, or settle for being marooned without product support? Time to move
off Lotus Notes and onto the cloud with Force.com, apps are easier to build,
use, and manage than apps on traditional platforms. Sign up for the Lotus
Notes Migration Kit to learn more. http://p.sf.net/sfu/salesforce-d2d
