Not entirely:
print "The color is ", param('foo');
print "The color is @{[ param('foo') ]};
Better yet:
use Template;
use CGI;
my $cgi = CGI->new;
my $template = Template->new(PRE_DEFINE => { cgi => $cgi });
$template->process(\"The color is [% cgi.param('foo') %]");
but that's my personal preference for most of my CGI problems, and this is
of course a trivial problem to be applying a templating engine.

I don't get this, what does unused code in a Perl script have to do with
network traffic?

I really can't tell you how bloated and/or inefficient CGI.pm is, if it is,
because I haven't done any testing, nor seen any done. However, hundreds of
thousands of hits in a week can be handled pretty easily by even a bloated
CGI script without affecting the server. If you meant to quote a larger
figure, indicating a heavily loaded site, then you really shouldn't be using
plain old CGI scripts. Your resources will get hit hardest by the constant
forking and execution of perl, not the code in your script.
