in thread Switch the odd/even elements of an array

This is a wonderful link, thank you. I'm getting way more out of this question than I expected.

Unfortunately, as I indicated in other replies, at my work the steel ball of perl destiny has fallen through the pachinko machine of corporate IT obstacles to land in the APATHY slot.

If there is one thing I have learned when I was a programmer, it was that life is much easier when external dependencies are minimized. bellaire has a nice essay (found via your link), but I think the reasons given for why one doesn't want an external dependency is a false dichotomy. Here's a real reason: Support is a non-trivial concern with module/library use. All that happy hoo-ha about generality and testing becomes secondary when the module isn't there. If you can't think of at least three reasons why a module wouldn't be where you put it, then you either aren't sufficiently imaginative or your corporate IT isn't sufficiently stultifying.

    ... life is much easier when external dependencies are minimized.

    What external dependencies? In an earlier link in this thread, you rejected consideration of a function like  List::MoreUtils::natatime because it was part of a module on CPAN. But I don't understand what difference that makes. Just Use the Source, Luke! Whether  natatime is really appropriate to the problem at hand is another question, but I just checked and as toolic pointed out, it's about half a dozen lines of pure-Perl, standalone code; if you need it, just steal it for Heaven's sake, that's what it's there for! (Although an acknowledgement of provenance is always a nice touch.) A simple cut-and-paste and you're done. And there's a ton more code where that came from.

    Perl is an external dependency, as is any code you copy/paste from here.
