// I wanted to use IME with my global constants (https://medium.com/@maxcampolo/fun-with-global-constants-in-swift-3e012aaec0c7)
// but not lose the functionality of catogories in my constants

// Problem:

extension String {
    static let string1 = "Test string."
}

let a: String = String.string1
