|Think about Loose Coupling|
I upvoted you because I used to be like you ;) And then I switched to CVS and haven't looked back since.
Even though I am the only Perl programmer here, version control does have a habit of saving my ass, no matter how careful I think I'm being. And once you're used to it, it's no more difficult than copying your files around. Actually, I find it less so.
Next project I'm off to try Subversion. . . ;)
But seriously, even if you're the only Perl programmer, give CVS or Subversion a look. Easy to use, easy to get going, and easy to be productive. You'll be happy you did.
