Range

A range is an object that represents a consecutive range of numbers. Syntax for this type has been directly inspired by Swift.

    // a represents a range with values 1,2,3
    var a = 1...3;

    // b represents a range with values 1,2
    var b = 1..<3;

    // Ranges have also a conveniente count property
    var n1 = a.count;   // n1 is now 3
    var n2 = b.count;   // n2 is now 2

A range is expecially useful in for loops:

    for (var i in 1...10) {
        // repeat for 10 times (with i from 1 to 10)
    }
