Kotlin Internal DSL - Create Your Own Language
summary
Kotlin features let an internal DSL compress a messy 20–30‑field data‑class setup into a short builder chain and make Android patterns like intent creation and activity launch readable and reusable. Examples show a date literal API (25 November), a plus‑days/oneWeek operator, a launchActivity extension that runs an intent block as receiver, and a UIState builder that uses apply and build; all use infix extension functions, lambda receivers and reified generics to remove boilerplate and run in real code.
