Initial implementation of boundaries operator in swift

BoundariesOp1.swift

struct LowerBoundary<T : Comparable> {
    let ls : T
    let rs : T
    var part : T {return rs}
    var isTrue : Bool { return ls < rs }
}

infix operator <& { associativity left precedence 200 }
func <& <Element: Comparable> (left: Element, right: Element) -> LowerBoundary<Element> {
    return LowerBoundary(ls: left, rs: right)
}

func <  <T : Comparable>(left: LowerBoundary<T>, right: T) -> Bool {
    return left.isTrue && left.part < right
}
