Extracting the marked region from the following code into a separate method 'foo'

 extension val x = newArrayList
 // ----8<----
 println(size)
 // ---->8----

will yield a method with compile error as the extension flag is missing on the method parameters:

 def foo(ArrayList<Object> list) {
    println(size)  // unknown method size
 }
