"Safer upgrade procedure
=======================
A safer approach is to add Python 3.13 support to your system first,
and only then remove Python 3.12. However, note that this involves two
rebuilds of all the affected packages, so it will take noticeably
longer.
First, enable both Python 3.12 and Python 3.13, and then run the upgrade
commands:
*/* PYTHON_TARGETS: -* python3_12 python3_13
*/* PYTHON_SINGLE_TARGET: -* python3_12"
It says "run the upgrade commands - COLON". As I understand English,
that says that what follows is a list of COMMANDS. And "*/*" looks like
a weird comment marker. Why would I assume it's a declaration snippet?
First, enable both python 3.12 an python 3.13:
<package.use stuff>
and then run the upgrade commands.
It is not lacking the quality of being idiomatic, to write the colon
after the full sentence rather than splitting the sentence in two. I see
both quite often. But regardless,
The problem is, if I see "commands COLON", that means that what follows
the colon is a list of commands. And it's clearly a list so I assumed it
was commands ...
From his name, I assume Michał Górny is not a native English speaker,
and I have no problem with that. I speak four languages to varying
amounts of ability and the quality of foreigners' English never ceases
to amaze me. But the fact remains I did not understand what this news
item said! It's been explained and it's now clear what was meant,
whether that's what was actually written or not.
And going back a bit - having carefully read the news item to find what
it said about package.use, it's magically changed!?!? I now can't find
any mention of "package.use snippets", which I am sure I found when
carefully reading the item!
But anyway - a bit more - the actual targets ...

That's basically what I got, except it was demanding python 11 or 12.
Given that I have absolutely no mention that I can find of python, in
either make.conf or package.use (other than the snippet I've just added
to force the upgrade), it looks to me like option 1 should have "just
worked". So why didn't it? Where else would there be stuff that tells my
system that Python 13 is "persona non grata"?
The only thing that feels like it might be a problem (and if Python 13
is now the default that's REALLY weird) is I don't have ~amd64 as
default ... (and my system is systemd/kde, but that also should be
irrelevant).
