may be i'm wrong
if B hasn't its initialize method, it's like you do
var instance = new A({child : A});
If your code is recursive the problem is not with mootools but ONLY with
your code.
quoting a wise: "...It gives you enough rope to hang yourself."
but if you cannot revise the structure of your code you can simply avoid the
recurring with something like this
if (options && typeOf(options.child) == 'class' && options.child!=A)
