Thanks for paying attention to every details!!
Actually, those things have been bothering me for quiet a while…
They are not reported by `./pre-inst-env guix lint python-pydantic` or
fixed by `emacs --script etc/indent-code.el gnu/packages/python-xyz.scm python-pydantic`. :-(

Would the following have been acceptable?

```

> +                "1380s9k77g6q15by9fkxndczjk89q6xpz09jdrqip535xws2z3j8"))))
```

And what about this? (2-space indent instead of 1, like `add-before` below)

```

```

Much better, thanks!
In retrospect, I realize that I should have put the question in the
commit message for a maintainer to read, not in the package definition.
Would that have been better?!

Sorry, I still suck at synopsis! :-(
