I can understand that you don't want to spend much time on it. How about removing it from 3.1? We could re-add it when long-term support becomes more likely.

I'm speechless. It seems that my statement has surprised you, so let me explain: I think we should refrain from making design decisions (such as API decisions) without Bob's explicit consent, unless we assign a new maintainer for the simplejson module (perhaps just for the 3k branch, which perhaps would be a fork from Bob's code). Antoine suggests that Bob did not comment on the issues at hand, therefore, we should not proceed with the proposed design. Since the 3.1 release is only a few weeks ahead, we have the choice of either shipping with the broken version that is currently in the 3k branch, or drop the module from the 3k branch. I believe our users are better served by not having to waste time with a module that doesn't quite work, or may change.

Most of my time to spend on json/simplejson and these mailing list discussions is on weekends, I try not to bother with it when I'm busy doing Actual Work unless there is a bug or some other issue that needs more immediate attention. I also wasn't aware that I was expected to comment on those issues. I'm CC'ed on the discussion for issue4136 but I don't see any unanswered questions directed at me.

I have the issues (issue5723, issue4136) starred in my gmail and I planned to look at it more closely later, hopefully on Friday or Saturday.

As far as Python 3 goes, I honestly have not yet familiarized myself with the changes to the IO infrastructure and what the new idioms are. At this time, I can't make any educated decisions with regard to how it should be done because I don't know exactly how bytes are supposed to work and what the common idioms are for other libraries in the stdlib that do similar things. Until I figure that out, someone else is better off making decisions about the Python 3 version. My guess is that it should work the same way as it does in Python 2.x: take bytes or unicode input in loads (which means encoding is still relevant). I also think the output of dumps should also be bytes, since it is a serialization, but I am not sure how other libraries do this in Python 3 because one could argue that it is also text. If other libraries that do text/text encodings (e.g. binascii, mimelib, ...) use str for input and output instead of bytes then maybe Antoine's changes are the right solution and I just don't know better because I'm not up to speed with how people write Python 3 code.

I'll do my best to find some time to look into Python 3 more closely soon, but thus far I have not been very motivated to do so because Python 3 isn't useful for us at work and twiddling syntax isn't a very interesting problem for me to solve.
