#43720 [NEW]: Abstract method argument ignoring

Bug description: Abstract method argument ignoring
Description:
------------
Related to: http://bugs.php.net/bug.php?id=36601
However, there's another case where it's nice if arguments for an abstract
method can be ignored. I'd call it a 'loose abstract method' and maybe
loose should be the keyword used to indicate it.
I bumped into this, when trying to make a simple container abstract class,
that could be extended for specific containers (see example).
Not only is typehinting a problem, since inheritance isn't checked, but
I'd like to be able to use more or less arguments depending on the
container type.
So I guess, this is a feature request for a 'loose' abstract method
declaration that simply ignores method arguments at compile time. The
implemented method still needs to be checked for any type hints though.
Reproduce code:
---------------
<?php
abstract class Container
{
protected $storage;
public $index;
public function __construct()
{
$this->storage = array();
$this->index = 0;
}
/**
* @brief setter overloader
*
* Guards index from going negative, instead it goes to end of the
array,
* minus the offset given.
*/
public function __set($nm, $val)
{
if( $val < 0 )
$val = count($this->storage) - $val;
if( $nm == 'index' )
$this->idx = $val;
}
/* loose */ abstract public function pushBack($thing);
}
class Cookie
{
protected $name;
public function __construct($name)
{
$this->name = $name;
}
}
class CookieJar extends Container
{
public function pushBack(Cookie $cookie)
{
array_push($this->storage, $cookie);
$this->index++;
}
}
$jar = new CookieJar;
Expected result:
----------------
Nothing.
Actual result:
--------------
Compile time error.
