Operator conflict if using the * operator for CGPoints

OperatorConflict.swift

import Cocoa

extension CGPoint {
    public func length() -> CGFloat {
        return hypot(self.x, self.y)
    }
}

infix operator ⋅ { associativity left precedence 140 }

public func ⋅ (lhs: CGPoint, rhs: CGPoint) -> CGFloat {
    return lhs.x * rhs.x + lhs.y * rhs.y
}

public func * (lhs: CGPoint, rhs: CGPoint) -> CGFloat {
    return lhs.x * rhs.x + lhs.y * rhs.y
}

public func / (lhs: CGPoint, rhs: CGFloat) -> CGPoint {
    return CGPoint(x:lhs.x / rhs, y:lhs.y / rhs)
}

let d = CGPoint(x: 1.0, y: 1.5)
let d2 = CGPoint(x: 2.0, y: 1.5)

var fraction = (d ⋅ d2) / d.length() / d2.length()
var fraction = (d * d2) / d.length() / d2.length() // <-- gives an error
