Playing with Experimental Kotlin Features
summary
Overview of concrete changes and how to try them: Kotlin 2.2 adds multi-dollar interpolation (use $$ to emit $ in multiline strings), guard conditions in when, and non-local break/continue for inline lambdas; enable experimental flags with -X or update to 2.2. The evolution repo shows ~49 open KEEPs so check proposals and UTRA for status. Upcoming: context parameters (renamed from context receivers), nested type aliases, and the must use return values checker (-X return-value-checker) with 2.3; name-based destructuring and rich errors target 2.4.
