This is somewhere between a question and a proposal. I'm just trying to understand why Path objects use an explicit iterdir method. Why not make them iterable? -- Vamsi

Because this is ambiguous. Iterating can mean many different things: 1. Iterate characters of string representation of the path (str(path)). 2. Iterate path components (path.parts). 3. Open a file and iterate its lines (path.open()). 4. Iterate files in the directory (path.iterdir()).
<devils-advocate> the same is true for files: Deciding to iterate them line-wise is relatively arbitrary, byte/char-wise would be equally intitive. So something could be chosen. </devils-advocate> But I think being explicit in the case of paths is really not that inconvenient. Serhiy Storchaka <storchaka@gmail.com> schrieb am So., 26.
