Introduction

Support default values for enum associated values.

        // The below code segment is an extraction from a compression routine for Ansi (ECMA 48) tags
        
        // For example: 
        // All Ps functions are compressed through summation of Ps values, for example:
        // \u{1b}[1C\u{1b}[3C\u{1b}[1B\u{1b}[1B\u{1b}[1B = \u{1b}[4C\u{1b}[3B
     
        // All CSI Pm functions are compressed with a semicolon delimiting sub Pm values, for example:
        //  \u{1b}[1m\u{1b}[30m\u{1b}[45m = \u{1b}[1;30;45m
        let tagArray = self.toString().characters.split(
           isSeparator: { String($0) == Ansi.C0.ESC } ).map { Ansi.C0.ESC + String($0) }

/*
 Behaviour below is consistent with inline declaration,
 index correctly mutates each interation
*/
for var index = 0; index < 10; index += 1 {
    index += 2 //mutable index
    print(index, terminator: " ")           // output = 2 5 8 11
}
print("")

private func handleNotificationAction(id: String?, userInfo: [NSObject: AnyObject], responseInfo: [NSObject: AnyObject]?, completion: () -> Void) {
    
    // inline our id choices
    enum idOptions: String {
        case comment, invitation_accept, invitation_decline, star, complete, show, delegate, none
        static var project: [idOptions] = [.invitation_accept, .invitation_decline]
        static var task: [idOptions] = [.star, .complete]
    }
    
    // Unwrap optionals
