pwagyi has asked for the wisdom of the Perl Monks concerning the following question:

In my team, there are a few programmers who do not follow any coding style guide. I am talking about using ALL CAPS variable/subroutine names(including local variables), overuse of global variables, manually re-inventing stuff (like parsing command line argument,), no design, no concern for DRY (a lot of repetition of code), stringly typed ( way of doing things.

I've been observing this for some time. I am afraid that it will only get worse. It also got me thinking such kind of code are what gives perl bad reputation as read only language. What should I do? should I just tell them quietly?
