And if we're going to continue being fair, using perldb inside emacs isn't so good with apache, becuase you need to run in single-process mode. If you've got some subtle problem with multiple apache processes, you're better off using it with the Tk front-end.

Setting breakpoints by clicking on a line sounds like an okay feature... I guess I might also like some sort of highlighting feature to see where breakpoints are set.

Nevertheless, I highly recommend using perl -d with *some* sort of front-end that shows the context of the code you're looking at so you don't have to keep punching the "v" command (I think it's "v"... used to be "w" for window, but now that's watchexpression).
