The API is exactly what I'd hoped it would be:-)
(So is there any need for codecs.open(), apart from backwards
compatibility?)
I've now updated library/functions.rst (change 59499) to reflect your
io.open() docs.
If you had the time you might want to check that I haven't said anything
untrue!
Unfortunately io.open() doesn't say what errors=None means. I hope it
means 'strict', but whatever it means, I'd like to specify the meaning
in the docs.
Thanks!
