public extension Swift.Optional {
    
    func nonEmptyValue(fallback: T) -> T {
        
        if let stringValue = self as? String, stringValue.isEmpty {
            return fallback
        }
        
        if let value = self as? T {
            return value
        } else {
            return fallback
        }
    }
