I'm curious as to other Monks views of Taint and it's usage. It seems to me that circumstances change dramatically whenever you are accepting user input of any form. Input can be coming in many ways, and be used many different ways on different types of systems. Also, scripts and users will have different rights and be located in different places. I guess what I'm trying to ask is, shouldn't you do your own taint checking every time you write a script that takes in user-input and have that taint checking be specific to your situation? If that's the case, then when would you need perl's taint checking? Do most Monks here rely on Perl for taint checking? Do you include your own?
