I use the same debugging and developing tools I use with Perl as I use with shell, awk, C, C++, Java, Python, SQL, HTML, Pascal, Ruby, FORTRAN, and whatever else I've coded in, as well: vi (or a vi-clone like vim, nvi, elvis) and print or assert statements. That method has worked for me for the past 25 years, everywhere. Be it Solaris, SunOS, AIX, SCO, HP-UX, BSD, Linux, Cygwin, and some (Unix) platforms I can't remember - basically, any platform I've used since 1980. Any platform I bother to sit down at has vi. Even when installed freshly out of the box.

I don't see a reason to switch away from a solution that's cross-platform, cross-language, works everywhere (well, everywhere in my world), is free (as in beer, often also in speech), has worked for the past 25 years (well, longer, but that was before my time), and will most likely work for at least till my retirement, and probably continue to work long after that as well.

But if Komodo works for you, go for it.
