List::MoreUtils::pairwise localizes typeglobs to *a and *b from the caller's package, which (I think) is a similar idea. For general parameter passing it seems a little outdated. Which version of Advanced Perl Programming? I don't remember seeing it in the 2nd Edition, and can't find it as I re-skim through the book. If you could provide a little more context (chapter, etc.) from the book maybe we could look to see what thought process went into it.
