message: "module `$M` is declared apart from the other module declarations"
note: Keep the module declarations of a scope together. Blank lines between visibility groups are not a split.
# An attribute counts as part of a run, which keeps a lone `#[cfg(test)] mod tests;`
# legal at the foot of a file. Comments are looked past instead, so that documenting
# a stray declaration does not hide it.
