mascip:

I'll go for the CPAN one for now, though =)

Good call! I only suggested it because it was the only thing I ever thought that symbolic references might be good for. But when I saw that toolic had a better answer, I just didn't feel like throwing it away. (It's the first time I've used 'em, and the fact that you need to declare the variables with 'our' instead of 'my' made me bang my head a bit trying to figure out why I couldn't get it working...)

When your only tool is a hammer, all problems look like your thumb.
