Kotlin - Advanced Tricks
summary
Shows advanced Kotlin idioms and patterns: using repeat instead of loops, also/takeIf/takeUnless for ordered side effects and conditional chaining, overloading operator fun invoke to make factories/renderers callable for DSL-style code, building HTTP endpoints as block-style actions with receiver lambdas, using the Nothing type to model terminal states for compile-time safety, and delegating function-like behavior to objects. Examples are runnable snippets demonstrating each technique.
