Why does Android Studio warn about freeCompilerArgs += listOf() ("creates new list under the hood") and suggests to change it to freeCompilerArgs = freeCompilerArgs + listOf() , I mean both create a new list?! Or does it warn because it's not obvious that a new list is created at first glance while the latter version is more explicit?
