Python post-Guido

My first thought was whether the Python 3 language should be declared finished? (Additions to the "batteries included" libraries still allowed, provided they do not ever break the older components).

Work could then start on Python 4, under a new management.

I don't know enough to recommend this, but an idea would be to call it "Mamba" instead of "Python 4" , and in the first instance to make its primary purpose the replacement of the Global Interpreter Lock with something that's more amenable to parallelization. Would this be more possible if some small parts of the Python 3 language were removed or redefined, in ways which still allowed the majority of Python 3 code to be re-used?

My second thought was of the Norwegian Blue parrot. I still don't know precisely why.
