Rich errors in Kotlin 2.4: say goodbye to boring try/catch or not quite yet?

Kotlin 2.4 introduces Rich Errors, a new error handling approach using union types that allows functions to return multiple possible types like `User | NetworkError | NotFound`. This feature makes error handling explicit at the type level, eliminating the need for Result wrappers or verbose sealed classes. The compiler enforces handling of all possible error cases, making code more predictable and type-safe. While currently experimental, Rich Errors offer a cleaner alternative to traditional try/catch blocks for expected business logic failures, though they're not suitable for truly exceptional system errors.
