Putting Down the Golden Hammer
summary
Shows concrete tradeoffs: examples of using explicit type annotations when complex reactive streams hide types, how nested scope functions (multiple apply/let) produces confusing receiver changes, when extension methods become inappropriate for business logic, and how Java interop yields platform types that tempt the double-bang (!!) operator. Recommends IDE type hints, prefer readability and maintainability over clever terseness, use requireNotNull or a single, documented assertion line for platform values, and favor intentional, minimal APIs.
