// Lower limit operator
operator infix |- {associativity right}
func |- <T : Comparable>(lowerLimit: T, value: T) -> T
{
    return value < lowerLimit ? lowerLimit : value;
}

// Upper limit operator
operator infix -| {associativity right}
func -| <T : Comparable>(value: T, upperLimit: T) -> T
{
    return value > upperLimit ? upperLimit : value;
}

_Limiter Operators_

The will work like this

var limitedNumber = 0 |- x -| 100

limitedNumber will be always in the limits including 0 ... 100

You can use the operators alone to just define a lower or upper limit

var lowerLimitedNumber = 0 |- x
var upperLimitedNumber = x -| 100
