Mobiconf 2018: Piotr Ślesarew, Grand Parade
summary
Concrete Kotlin tricks and caveats: practical differences between let vs run vs also vs apply with examples showing when lambdas receive it or the receiver and why apply suits initialization; using Pair/destructuring to flatten nested when chains but warning about extra allocations and non–exhaustive matching; data class componentN generation shown by decompiled bytecode; typealias is just metadata so extensions leak onto String; reified generics let the compiler emit runtime type checks; custom property delegation by KProperty works but delegation by reference uses reflection and can hurt performance.
