DSL Builders, Inline Functions & Operator Overloading

Learn how Kotlin's lambda-with-receiver syntax enables elegant internal DSLs — the same pattern behind Gradle KTS and Jetpack Compose. We cover inline functions in depth, explaining how they eliminate lambda allocation and enable non-local returns. Operator overloading is demonstrated with practical examples like custom vector math and range iteration. You'll leave able to design expressive APIs that read like natural language.
