Re^2: Perl's changes in the use of packages

I'm not sure what's the OP's benefit, but I've witnessed the drawbacks of not doing so:

You can't use modules from CPAN, at best you need to search backpan for old versions (in my case, our client switched from FTP to SFTP);
You can't switch to a new OS version or architecture smoothly (see The Unicode Bug with Transliteration or Substitution for an example);
Old security bugs lurking (hash randomization etc.).

All valid points. I am of course not suggesting to never update your Perl version. But I would think that for the OP, given how he described his code, keeping up with the very latest Perl might be unnecessarily far in the other direction. The way forward always starts with a minimal test.	[reply]
