I'd be fine with the swearing if it'd be backed up by some knowledge and experience, but that smug attitude is just incredibly irritating when coupled with such level of ignorance. First decide what are you going to bash. Some libraries, some applications, the entire programming environment ? Using induction from DBI->quote/CGI and a few old apps to bash the entire Perl ecosystem is just boringly stupid. It is fine and useful to patch those old apps, but to give an arrogant lecture as if all programmers use the same broken approaches in 2014 is just ignorant.

It is extensively documented to prefer placeholders when working with DBI, that is, if you even use DBI directly and not via an OO mapper. CGI as an approach is entirely deprecated on all languages/platforms not just Perl. List expansion ? It is a feature, use it or leave it. You have the option to use references. If you prefer Python, just use Python. It's like bashing C for having pointers. So, what else ? Try PHP with those examples. Find some Ruby apps prone to sql injection. Bash some NodeJS libraries. If Perl is dead already, be a rockstar bashing the new stuff, why even bother with the ghosts ? I think it is because deep down all Pythonistas know that Perl is a far superior platform and they all carry a deep ancestral envy. Otherwise they'd just be happy with their choice already. :)
