Something like CGI::Simple means a good chance that the user has to install it.
Depending on what you're doing, that may not be a real
issue, since you may by virtue of your requirements
already need some non-core modules. For example,
Bugzilla, no matter how it was done, could not have
gotten away without at least one non-core DBD module,
and practically it really had to have a datetime module
as well. (I don't happen to know which one it uses.)
If your project has this sort of situation, you can
use any module you want that's on CPAN, _especially_ if
it's pure Perl, and then create a Bundle:: module that
pulls in every module you use. The user doesn't even
have to _care_ what individual modules you've used;
they just install Bundle::Whatever like your install
instructions say, and off they go.
OTOH, if you're only using one non-core module and you
can easily avoid it by using a core module instead, by
all means, do that.
As far as CGI.pm, I got so disgusted with it after
seeing the output of some scripts that use it, that
I have never even contemplated pondering the possibility
of considering ever using it myself. Maybe the authors
of the scripts in question used CGI.pm wrongly, and
maybe I'm doing CGI.pm an injustice, but CGI is such
a simple thing, it wasn't at all difficult to roll my
own solution, which handles everything I need (yes,
including cookies, which are stored in a MySQL db;
my login/logout box is a self-contained function so
the user can log in or out from any page that contains
it.), runs in taint mode (using Taint to taint the input
after parsing it into key/value pairs), returns the
form input as a nice tidy hashref, and produces nicely
formatted human-readable output that validates. I
thought about distributing it, but there are so many
implementations already for this... probably because
it's such an easy problem. CGI was designed to be
easy to implement.
