Issue Description:

On swift 5.0

This code doesn't compile due to error "Compiler is unable to type check this expression in reasonable time"

import Foundation


let padding: CGFloat = 1
let stroke: CGFloat = 15
let origin: CGFloat = 2
let handleViewHeight: CGFloat = 1


_ = CGPoint(x: 1, y: (origin + (padding + handleViewHeight/2 + stroke/2))/1.75)

But on swift 4.2 compiles without any problem.
