There is no reason I can possibly imagine why methods declared as static
should be allowed to be called from a non-static context. Sure, in my
own classes I know not to call a method I declared as static from an
instance. But IMO the whole point of static is to create a restriction
in then engine keeping from anyone calling that function in anything
other than a static context. 

class foo {
	static function bar() {
		echo "Hello.\n";
	}
	
	function foobar();
}

$a = new foo;
$b->bar();

This is a completely acceptable thing, and it is IMO completely wrong to
even allow in the engine. foo::bar() should be the only accepted syntax
for static functions. If I download a new class from some site, or
otherwise use someone else's code, how do I know other than digging
through the source on a method's context? If $this isn't set I can't do
the check, and if then engine doesn't do it there isn't a way to tell
the difference.
