Reports if, when, and try statements that can be converted to expressions by lifting the return statement or an assignment out.

Example:


  fun foo(arg: Int): String {
      when (arg) {
          0 -> return "Zero"
          1 -> return "One"
          else -> return "Multiple"
      }
  }

After the quick-fix is applied:


  fun foo(arg: Int): String {
      return when (arg) {
          0 -> "Zero"
          1 -> "One"
          else -> "Multiple"
      }
  }

If you would like this inspection to highlight more complex code with multi-statement branches, uncheck the option "Report only if each branch is a single statement".
