    Drastically reduce the amount of boilerplate code

    /*

    */
    
    data class Customer(val name: String, val email: String, val company: String)
    
    // Or filter a list using a lambda expression:
    
    val positiveNumbers = list.filter { it > 0 }
    
    // Want a singleton? Create an object:
    
    object ThisIsASingleton {
        val companyName: String = "JetBrains"
