in thread Don't use 5.6.N

"Can't find warnings.pm..." is a better error message than "Perl 5.006 required", IMHO (much more specific). And I can trivially arrange for code that does "use warnings;" to actually work quite fine on an installation of Perl 5.005, so leaving off "use 5.006" would make the code better in two ways.

Though some people seem to be offended in some way that some people have reasons for using older versions of Perl and your "dumbass" comment indicates that you are likely one of those.

    The dumbass comment was for the person who threw in "use warnings;" without protecting for it. That's aimed at all those CPAN devs who have "use warnings;" in their tests, but not in their code. Running on older Perls is something I fully respect and understand why it happens - both PDF::Template and Excel::Template run perfectly fine on 5.005_03 and I think they'll run on 5.004 (though that's untested). I also know what I went through to get there.

    As for it being a poor error message - that's from experience. I've gotten a lot of "Why is this breaking on machineX when it works on machineY?" as a consultant. A simple "use 5.006;" would've fixed everything. I view it as documenting assumptions through assertions.

    My criteria for good software:
    1. Does it work?
    2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
