Hi Guix!

I'm currently working on packaging Python 3.11. It seems to produce a
working `python3`, but there's still a lot I have to work on!

I had to copy/paste 3 snippets (see `TODO`) just to modify a few lines in them.
The problem might come from the fact that this package definition
inherits from `python-3.9` that itself inherits from `python-2`.
Might also be because I'm still (really) bad at writing scheme/guile code! ^_^'

This leads me to my first question: wouldn't it be better to write a "fresh"
package definition not inheriting from `python-2` (deprecated since 2020) and
`python-3.9` (soon to be replaced)?

Another question would be: should I first write a package definition for
`python-3.10` so we have it in the history and one could use the time
machine to install it?

Any help or advice would be highly appreciated!

Best regards,
Tanguy

Yes, it would be nice to have Python 3 as the package definition. And
maybe Python 2 as inheriting from Python 3. :-)

Well, it appears to me fine to jump from 3.9 to 3.11 dropping 3.10.

Hi Simon,

Believe it or not, I sent the patch before I went on vacation and… I kind
of forgot about it! 😅
