New submission from Davide Rizzo:
pathlib doesn't provide an exact replacement for os.path.realpath().
Path.resolve() is the closest equivalent, but differs in behavior in one case:
when the path does not exist.
>>> os.path.realpath('/foo')
'/foo'
>>> Path('/foo').resolve()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File

FileNotFoundError: [Errno 2] No such file or directory: '/foo'
This impairs pathlib usefulness to sanitize user input when I am about to
create a file or a directory. The file does not exist yet, and pathlib doesn't
provide an easy mean to validate whether the provided input is safe.
