which is slower.
what might be nice is a special function modifier (just thinking out loud):
autoargs function __construct($x, $y, $z) {
$this->foo = 'bar';
}
which would be equivalent to:
function __construct($x, $y, $z) {
$this->x = $x;
$this->y = $y;
$this->z = $z;
$this->foo = 'bar';
}
but it's such a simplistic idea that its probably
not worthy - in practice objects don't often taken that many args
and more often than not you [should be] doing some sanitation
of the args.

you might consider a meta class concept - write classes that are used as configurations
add/update boiler-plate init code for classes.
MetaCls () {
$args = array('x', 'y', 'z');
}
