I equivocated in my post to the OP.
I also don't see any "necessary evil"
Some Perl libraries like File::Find do chdir's for their work and error recovery from a something like that can be very problematic because you can wind up in some random directory. The &wanted routine should be as simple as possible to avoid this problem.
In general, chdir is a bad idea.
I could think of situations where a chdir to a program's data could simplify the code slightly, but I also don't see "necessary evil", meaning "required".
