  while, technically, that's a correct answer, it's also worth
suggesting that, if you truly need to distinguish between your
prerequisites that way, there's possibly something wrong with your
design.

  prereqs should, in an ideal world, simply represent a set of
unordered dependencies.  if you're insisting that they have a
particular order and you want to examine that order, i think you're
just asking for trouble.
