I had a serious look at Eclipse with the intent of using it at work, but at the end of the day (a rather frustrating week actually!) I was editing Perl with it and could run the code, but I couldn't get break points working so I couldn't debug it. Of less importance, I was fighting with the IDE in various ways too, but that would have sorted itself out in time.
Other workmates have used Eclipse in other contexts and are very impressed with it, I just couldn't get it to do the job for me with Perl. However, having just purchased a Handspring Visor which runs Palm OS, I may find a different reason for using Eclipse :).
Perl is Huffman encoded by design.
