io and _pyio modules don't usable without the _io module. In particular when 2.7 build without unicode. Why we have a Python implementation if it can't be used as a fallback when a C implementation is not available?
benjaminp commentedon May 15, 2013
Well, we at least need some C level _fileio.
alex commentedon May 15, 2013
I don't see why we need some C level _fileio, the os module has everythign we need.
benjaminp commentedon May 15, 2013
Patches welcome, of course!

Serhiy implemented the FileIO class in pure Python: see the issue bpo-21859 (patch under review).

_pyio(Python implementation) still does animport iowhich unconditionally imports_io(C implementation) so I'd argue still not pep-399 compliant.pythongh-62184: Remove _pyio import of _io.FileIO (pythongh-134192)
