The rationale behind asking about unsigned is that I would consider something like 'child[-42]' weird. My intuition was that this is something that the community considers not important enough to invest in. If we don't want to leave it as is, I would prefer some proper fix (explicit limit on the number of hotplug operations, or scanning for the first free one). Regards, Halil
