Example where you may sometimes need is_dir(), but not always

That is an extremely good point, and articulates why I've always been
a bit uncomfortable with the whole ensure_stat idea.
On a system which did not supply is_dir automatically I would write that as:
for entry in os.scandir(path): # info defaults to 'os', which is basically
None in this case
if ignore_entry(entry.name):
continue
if os.path.isdir(entry.full_name):
# do something interesting
Not hard to read or understand, no time wasted in unnecessary lstat calls.
