How would you implement a type-safe Kotlin DSL for a UI Form?
Tests Kotlin DSL scoping with lambda receivers and extensions. Strong answers sketch a Form builder using initTag, explain T.() -> Unit implicit this for child elements, and add DslMarker to block scope leaks. Red flag: describing it as simple method chaining.
Tests deep knowledge of Kotlin DSL construction through lambda with receiver and extension functions. A strong candidate designs a Form builder where top-level form lambda receivers expose textField and button methods via extensions, uses an initTag helper to instantiate children and execute their T.() -> Unit block so implicit this scopes correctly, and applies DslMarker to prevent cross-nesting between sibling scopes. Red flag: confusing DSL structure with standard builder pattern or omitting scope control entirely.
