The same way += et al. are in-place: it would ask 'x' to modify itself, if it can. If not, no harm done. (It would be called as 'x = ipow(x, n, 10)' of course, just like 'x += n' is really 'x = x.iadd(n)')

I think this would violate the policy that a mutating function shouldn't give the object being modified as the result - just as list.reverse doesn't return the list, in addition to reversing it in-place.
