The pickle documentation says that the first argument to dump and dumps is called "object", but both the pure-Python pickle module and (now) the cPickle module call it "obj". The pickle module purposely calls it "obj" instead of "object" to avoid shadowing the "object" builtin, and the cPickle does likewise to maintain API compatibility.
