that is why I already use Obejct.create in vice-versa only if not defined
and when it will be standard the jQuery way will be simply this one:
$.extends(Object.create(proto), props);
the bedge callback was just an optimized suggestion over a snipped based on
a dated proposal.
Regards
P.S. not sure if Object.create will support directly the extra argument, I
have implemented it without classic toString and other failures
