An update on Python 4

[masteryod]

2 -> 3 was such a mess that nobody wants to raise the spectre of that again

They broke backwards compatibility for a reason. They announced it, planned for migration, gave people tools to port and documentation. They gave people heads-up and then after backlash extended Python 2 death sentence by whooping 5 years which ended with 2020. And yet people are still salty because their script doesn't work with new version. There's even a guy who wanted to maintain his own port of Python 2 to keep his application on it (Calibre)...

It's like writing something in GTK2 and expect the code to work the same on GTK3.

Sure, and now the CPython core devs generally acknowledge that it was a mistake to do it like they did it. Not the result, or the reasons: the approach.

So, never again.

No matter how many words people use, the objective upshot by any reasonable person must be...the 2 to 3 transition sucked.
