[Python-3000] How to override io.BytesIO and io.StringIO with their optimized C version?

["Martin v. Löwis"]

> Why wait until 1.0? 

When I suggested moving from CVS to subversion, people asked that
a PEP is written; this became PEP 347.

I would like to ask the same for any conversion *from* subversion,
be it to hg, bzr, git, bk, or ClearCase.

So anybody who wants to seriously attempt introducing such a change,
please present your PEP. Anybody else, please stand back and watch.

Regards,
Martin
