Effective Kotlin_PiP
summary
Shows how Kotlin stops bugs with concrete techniques: replaces primitive ID mixups by wrapping longs in sealed classes for ID validity and extension properties so the compiler rejects swapped args; uses when-as-expression to force exhaustiveness; recommends Arrow and demos Try and Option from Arrow to model failures and nullable streams; builds test helpers with infix extension functions against MockWebServer and RxJava; points to inline classes (Kotlin 1.3) and delegated properties like a Bundle string delegate to remove boilerplate.
