interface Entry 
  function __construct($name, $path);
}

class Folder implements Entry {

  var $name = '';
  var $path = '';

  function __construct( $name, $path ) {
    $this->name = $name;
    $this->path = $path;
  }
}

----well, if you are implementing something completely new in php5, there there
are no compatibility issues.  I have many classes in my projects in php4.  I'm
not sure of how many child constructors have different parameters (my guess is
not many), but enforcing strict parameter count for childs classes would break
compatibility.  Which is why I think that one should just use an interface to
enforce this rule.  It seems like the right place for it.
