PERL-CGI learning

Hi, as bakunin points out above CGI programming is language agnostic and I have also used everything from Bash to C to define CGI responses, however Perl is particualrly suited to the task and the good folks over at Perl Monks provide a useful list of tutorials on how to use Perl for CGI (including Ovid's excellent guide to not shooting yourself in the foot 
)
However once youve grasped that CGI is essentially a remapping of STDIN and STDOUT and the basics of Perl (or your chosen language) there have been a number of improvements in Web Development made over the last 15 years and plain CGI scripting is probably not the most efficeint way to go learning a module/Framework like Dancer or Catalyst makes for maintainable code.
