Anonymous objects in the scope of an inline functions are copied to all call-sites. This makes them part of the public ABI of a Kotlin library. We introduce a flag to mark all classes in the scope of an inline function. When compiling with assertions enabled, we check that this flag is set whenever we inline an anonymous object from another module.
