10/20/2022, 4:18 PMAnd, of course, a little speedup is nice too:
CPython 3.11 is on average 25% faster than CPython 3.10 when measured with the pyperformance benchmark suite, and compiled with GCC on Ubuntu Linux. Depending on your workload, the speedup could be up to 10-60% faster.https://docs.python.org/3.11/whatsnew/3.11.html#faster-cpython

10/20/2022, 4:22 PMI think the speedup is the most impactful feature for Meltano and our other open-source Python projects. We can't use many of the new features yet because we still support Python 3.7, but we don't have to do anything to get the benefits of the performance improvements. It's free.

10/20/2022, 4:36 PMI'm tentatively excited for exception groups personally. I've had many occasions where I'm doing parallel/concurrent processing (threads, subprocesses, sub-interpreters, no-GIL C code, asyncio, etc.) and there's a possibility (or even an expectation) that multiple exceptions are raised and need to be handled together. My approaches to these issues have always felt half-baked, and so there being a standard way to handle these cases now seems nice.

10/20/2022, 4:38 PMPython's (deserved) popularity as a glue language has made it such that it has to handle (or at least many people want it to handle) a very wide breadth of use-cases it was never originally designed to handle. Some of the solutions are kinda clunky, but still better than no solution.
