Or the ever popular symlink to "." (or a directory higher in the tree).
"." and ".." are explicitly ignored by os.listdir() an os.scandir().
I think os.walk() is a good source of inspiration here: call the flag "followlink" and default it to False.
IMO the specific function os.walk() is not a good example. It includes symlinks to directories in the dirs list and then it does not follow symlink, it is a recursive function and has a followlinks optional parameter (default: False).
Moreover, in 92% of cases, functions using os.listdir() and os.path.isdir() follow symlinks: https://mail.python.org/pipermail/python-dev/2014-July/135435.html
