What are you saying here? That CPAN modules should require as many
dependencies as possible, so no one can use them without installing a
list of other modules? That's a good way to minimize your user base.

Reinventing the wheel is not a good thing. But many wheels are just
waiting to be reinvented. I recently sought a module to parse CSV
files. There are several on CPAN, but none of them support newline
characters inside a CSV field. It's allowed in CSV, it happens, and I
need it. They also wrap an XS module, which would require me to build
and install it separately for each platform supported.

So I wrote my own parser. It only took a few hours, and it does just
what I need. It would have taken me as long to install and test the
CPAN modules anyway.

Reuse is good, but reimplementation can often be better.
