# NOTE: The following is a hint that will be printed by the Nix cli when
# encountering an infinite recursion. It must not be formatted into
# separate lines, because Nix would only show the last line of the comment.
# An infinite recursion here can be caused by having the attribute names of expression `e` in `.overrideAttrs(finalAttrs: previousAttrs: e)` depend on `finalAttrs`. Only the attribute values of `e` can depend on `finalAttrs`.
