These kinds of advancements in the language are why I'm glad I've switched to Python 3, Python 2 needs to die already.

  Python 2 will never die. Ask Kenneth Reitz for example. He says he will use Python 2 forever. There are a lot of companies with huge codebases who never will port to Python 3.

    This is the unfortunate truth. My company still uses Python 2 solely, not a single line of Python 3. Unless there is some major breakthrough in porting tools (in combination with more and more libraries supporting 3), Python 2 will still probably be the only Python version in many enterprises for the next 10 years.

    > Python 2 will never die. Everything dies. > Ask Kenneth Reitz for example. He says he will use Python 2 forever. So, assuming this currently-stated intent never changes and Reitz is immortal, Python 2 will always be in use. The first of those premises is somewhat suspect, the second even moreso. > There are a lot of companies with huge codebases who never will port to Python 3. That's probably true. Its less likely true that those companies will never port off Python 2.

      > Everything dies Python itself might die when Python 2 dies, and arguably, Python 3 makes that more likely.

    In my job we have some big projects on Python 2 and Cython gives us access to some of the "new Py3 features": types (real types, not just hints) and async IO (through C primitives). We eventually chose Cython because at least we can get big speedups (depending on the code and how much can be properly cythonized, of course). With Py3 it was a change to the codebase (which we also had with Cython, of course), to get approximately the same performance, maybe slightly less, maybe slightly more.
