"${stuff[@]}" would be turning it back into "foo bar baz" though, right? I think if you were using arrays for this, it'd be something like: stuff=("foo" "bar" "baz"); array_le

Even in situations like that one, I think it's possible to avoid the comment: - setting up a type (with a comment linking to that API's documentation) - setting up a shape validator & a test that asserts that that that field i
