/// This property means it is often more useful to use `!file_type.is_dir()`
/// than `file_type.is_file()` when your goal is to read bytes from a
/// source: the former includes symlink and pipes when the latter does not,
/// meaning you will break workflows like `diff <( prog_a ) <( prog_b )` on
/// a Unix-like system for example.
