> In both cases, the object does not exist, so no error should be reported IMO.

But given the ever-present possibility of human error in composing the request, distinguishing between "found the thing, deleted it" and "couldn't find the thing" seems important: if I meant to delete "foo" but the command I actually typed said to delete "fooo", I might want that to be an error, to shake me out of my lethal complacency and alert me to the fact that "foo" with two 'o's might still exist.

We could have swiftclient give a special, more-specific error message in this case of 404 on DELETE?
