I think the point many are making here is, if you're going to break compatibility as was done with Python 3, then fix the underlying issues with the implementation. - Python 2 calls out to C code alot? Ok, rebuild the interpreter in such as way that allows for a JIT. Prevent callouts to C or severely limit them. JITs are mature technologies now, many dynamic languages have it. - Remove the GIL, make it fan out for multicore. - Add a Generational Garbage collector, remove the reference counted one with timely finalization. - Add back all the missing features for FP that people are asking for. If you're going to break compatibility, don't take half-measures, go all the way.
