Sounds a good idea. $super though is identical to $this in plain value but
has a different type.
For $super you mean $this but treated as if it were a parent class. Maybe
this will be introduced soon.

As you indicate it will be difficult to do automatically, however you can do
as perl does and just analyse the arguments yourself and then call a
different internal implementation.
function foo($foo1,$foo2=FALSE) {
if ($foo1 == "oik") return $this->_foo_1($foo1,$foo2);
else return $this->_foo_2($foo1,$foo2,"bink");
}
You can also make use of func_get_args when writing your own dispatcher
(http://www.php.net/manual/en/function.func-get-args.php)
This would me more clear than anything you could hope to get in a type-free
language.
