That syntax made my eyes hurt, but I think really the problem is that
people want to dynamically add methods with $this in the closure
pointing the the object it has been attached too. Really I like A. but
can see cases for rebinding (C). Maybe a magic method like
__attach(string methodName, function method) that would rebind $this
in closures would be a solution. But it would be the first magic
method I can think of that isn't overridden by the defining class.

$o = new StdClass;
$o->bar = 'bar';
$o->__attach('foo', function() { echo $this->bar; });
$o->foo(); // bar

Just a thought.
