Bug description:  Fetch multiple elements from an array

I was thinking about a new feature. Fetching multiple elements would be a
cool feature, wouldn't it? This would look like this;

  $array[0,1];

or

  $array['name','address'];

and would allow constructions like this:

for($i=0;$i<count($array);$i+=2) {
  list($odd,$even)=$array[$i,$i+1];
}

instead of:

for($i=0;$i<count($array);$i+=2) {
  $odd=$array[$i];
  $even=$array[$i+1];
}

This syntactically follows the specification of using the "comma" to
provide multiple elements/indices, such as it's already the case for
functions. Therefore adding this feature wouldn't deteriorate the
code-readability.

Also, I cannot think of any way using this feature to encourage bad coding
practices.

$array from the above example could be a datafile from a guestbook where
always a pair of lines represent "username" and "comment" (instead of using
"|" or anything else as a delimitor).

Your comments?
