Submission: switch (...) instanceof feature

[Artur Biesiadowski]

1) Why case void: instead of case null: ?

2) What is a expected behavior in case of multiple matches ? For example

switch(collection) instanceof {

case RandomAccess:
    ...

case List:
   ...

case Collection:
  ...


}

Do I need to put switch cases in correct order because of top-to-down 
evaluation or most specific one will be used? Or maybe all matching ones ?

3) I think you have forgotten to put 'break' in your examples, unless 
you plan to disallow fall-through.
