Subject: Unexplainable array phenomenon

hey folks, perhaps I'm too overtired, but I've got an array problem
where I can't see my error

class Main
$someArray=[]
$someArraytmp=[]


 def someMethod(elem,k)
    $someArraytmp[k] = elem
    if(k==0)
      $someArray.push($someArraytmp)
      $someArray.each {|e| p e}
    end
  end
end

t= Main.new
t.someMethod("hello", 0)
t.someMethod("bye", 0)


From my opinion there must two arrays in the global (array)variable
$someArray.
The first array element should contain a String hello at the first
position.

The second array element (in $someArray) should be a String bye also at
the first position.

So:
$someArray[0]
 -> []
       -> "hello"
 -> []
       -> "bye"


But after compiling it there is

$someArray[0]
 -> []
       -> "bye"
 -> []
       -> "bye"

can someone explain to me why this happens?

thanx sala
