Reproducer

I tried this code:

fn foo(from: &Path, to: &Path) -> io::Result<()> {
    make_fifo(to).and_then(|_| fs::remove_file(from))
}

I expected to see this happen:

Warning, with a suggestion

fn foo(from: &Path, to: &Path) -> io::Result<()> {
    make_fifo(to)?;
    fs::remove_file(from)
}

Instead, this happened:

No warning
