It'll be supported by RHEL well into 2027. I don't have to care much about it.

Py3 is not really a different language, it's the same old Py2 with added inconvenience. I've done migrations Py2->3 and haven't found anything worth the effort so far. And I really detest the efforts to force the migration by actively making Py2 more and more inconvenient to use.

Personally, a major motivation for me to finally switch to PyX would be GIL removal.

that's, like, your opinion, man

seriously, I'd love to drop python 2 to be able to use generators to their full advantage (`yield from` would make my code so much cleaner)

so, sorry, but if you really think that Py3 is just py2 with few "inconvenient" items added then I don't think you can claim to know Py3

well, it won't happen in py2.7, that's certain

Something tells me that you never ventured outside of writing English, because in any other language, having strings in unicode rather than ASCII is a huge improvement.

Then, Python3 has type annotations, which lets you use mypy to do some static checks on the code.

I wrote typedload (https://github.com/ltworf/typedload) to load json-like data into typed data structures, so that once loaded, you know your data has the correct types and can be safely be passed around.

My grandmother did not know how to use a computer, that doesn't mean that computers are useless.

JFYI, my native language is Russian so I’m acutely aware of encoding problems since so many of them were used for Cyrillic scripts. I can speak Ukrainian and understand Polish and Czech. I’d used to be able to speak German but haven’t practiced it in decades and lost most of it. Now I’m also studying Mandarin Chinese for a change.

Static annotations are nice, but are kinda beside the point.

Except that Python 2 strings aren't ASCII and support Unicode perfectly well: you just put UTF-8 inside them.

They work but are very error prone, because characters might take any amount of elements, so you have all sort of issues when doing cycles or manipulation.

With unicode objects, you know that they are not array of bytes and a conversion is needed, and you get an error if you didn't do the conversion that you were supposed to do.
