Even more shenanigans when self is not required

gistfile1.swift

// MyClass.swift

class MyClass {
  func doSomething() {
    refresh()
  }
}

private func refresh() {
  println("I'm the global refresh function.")
}


// main.swift

// Oh dear, we didn't know that there was an internal private function called refresh...
extension MyClass {
  func refresh() {
    println("I'm an extension refresh")
  }
}

MyClass().doSomething()

// And our refresh() gets called. I wasn't expecting swizzling to happen quite so subltly.

Same here... global function names should start with an uppercase letter, instance names with lowercase letter. Can we move on, please :)
