There are days I use Data::Dumper and print statements, but there are many more days that I use ptkdb. Once I found ptkdb, I was in heaven. No more sprinkling multiple print statemens throughout my code that I have to take out later.

The editor I'm using has it's output window as a child window in the editor so when you do lots of print statements, you either watch them fly by or you get to scroll through them to find what you're after. With ptkdb, even if I'm watching complex data structures, somehow it's more pleasing to me to be able to see what the variables are doing as the program runs, than having to rely on print statements to watch.

Now if I could just find one that would work for tracing Perl/Tk variables as the program runs...
