  >   Hmm, I feel like there was a previous version that iterated differently and meant I'd need a copy of the list to do this correctly.. in this version, no I don't think there's a reason to avoid it besides a potential minor speed difference; should I send a patch for that?
  
  I don't have any preference, but please send a patch if that makes sense,
  thanks.
