It's inlined below, and it will probably appear soon at http://www.python.org/dev/peps/pep-0455/, too. Regards Antoine. Hello. Overall I think that's a great idea. Here are some questions on it though. I'm sorry if some of these have already been discussed in some other thread. 1. Thread safety. PEP doesn't mention anything about thread safety while the implementation proposed in the tracker is (very) not thread-safe. I think, PEP should mention that this class have no guarantees. 2. Extra dict. There should be a way to avoid creation of the second dict when there is no need to store original keys. For example, email.message module doesn't store original headers as they are not needed. The same applies to web frameworks parsing HTTP headers or WSGI environment.
If you don't need the original key, then you might as well just use a transform function with a dict.
I'm sure I had another one. I'll send it once I remember.
