Personal opinion: cl-fad was a great improvement when it first appeared, but it has way too much implementation-dependent pitfalls. I recommend uiop, which is of vastly higher quality, and also has the advantage of already be in your implementation as part of asdf 3. And if you need finer control on filesystem access, use iolib. — Fare Rideau
