I get a different error message (wrong # of arguments) -- but in any
case, keep in mind that when you call "super", you're already calling
Array.[] -- so if you add [*a] to that call, you're doing:

  Array[1,2,3][1,2,3]

If you just use "super" by itself it will automatically propagate all
the arguments up to the super method.
