It's a side affect, I don't think we should document this :-) (Also, don't rely on this behavior)

Funny side effect :)) By the way this behavior may cause some problem:

function Test()
{
  $res = some_user_func();
  return count($res) == 1 ? $res[0] : $res;
}
list ($a) = Test();

If some_user_func returns "array(1,2)" then $a will contains '1' but if it returns array('Test') then $a will contains 'T'.

I think it will be better if PHP cause notice or something in this way or make right type conversion.
