I'm happy to bang out thousands of lines of code in sessions that last hours on end. The first two lines are always
in reply to Taint mode... use all the time?
But I'm just too lazy to type -T on the command line. Weird.
But in all seriousness, in my personal programming style, I don't want anything as strict as taint checking. I write most of my code for myself, to run as myself. You could say, "turn it on if you're writing a server," but if you really care I would say that as, "turn on taint if you're accepting input from someone else." Servers, scripts running under servers, or clients communicating with other clients.
