[issue32509] doctest syntax ambiguity between continuation line and ellipsis

Jason R. Coombs added the comment: Today I encountered another situation where it would be convenient to allow an ellipsis at the beginning of the syntax: >>> pathlib.Path('abc') ...Path('abc') Because pathlib.Path resolves to `PosixPath` and `WindowsPath` depending on the platform, it

New submission from Jason R. Coombs : I'm trying to write a doctest that prints the hash and filename of a directory. The input is the test dir, but due to the unordered nature of file systems, the doctest checks for one known file: def hash_files(root): """
