Hi,

remember a saying like "avoid calls like (eval 'my-symbol) in
lisp-code" as related to security issues.

Is there some reading to learn more? Maybe I'm mistaking something?
Perhaps because a randomly downloaded package can redefine 'my-symbol
to be something evil?

Yes, that would be the problem. However, the way Emacs works, any symbol might be replaced by such a package, right?
