Two Stones, One Bird: Implementation Tradeoffs
summary
Compares concrete Kotlin choices: null handling (if vs ?.let), scoping helpers (with / apply / run / also), primitive vs boxed arrays, delegates.notNull versus lateinit and inline function vs property tradeoffs. Shows bytecode for if and let, finds an extra bytecode assignment removed by ProGuard, reports a 93% poll favoring let, and argues sequences avoid intermediate lists but add lazy-transform overhead—so performance wins require profiling; recommendations favor readability unless measurements prove otherwise.
