basically we need _since to add the kind of functionality we have in Slice (or will, after 261 is committed). it's probably better to get 240 (and 185 + 189) done sooner than later though instead of wasting effort on an API we know is broken. (the old get_slice could do basically anything since it deserialized the entire CF into memory. we're moving away from that to support larger-than-memory CFs.) -Jonathan
