Hey Ludo,

yes it should. It’s the next logical step after having a
pyproject-build-system. The python-team branch (not sure whether Ricardo
had time to merge it yet) adds a TOML parser to Guix as a first step.

The file is always a trampoline to other build systems, like setuptools
or poetry. That’s (unfortunately) by design, see the [build-system]
section.

> [tool.poetry.dependencies]
> python = "^3.8"
> Jinja2 = "^3.1.1"
> Mako = "^1.1.3"
> tornado = "^6.0.4"
> six = "^1.15.0"
> coverage = "^6.3.2"
> nose = "^1.3.7"
> Flask = "^2.1.1"
> charset-normalizer = "^2.1.0"
> flake8 = "^4.0.1"

That’s unfortunate, because the
specification includes a common field for dependencies:
https://packaging.python.org/en/latest/specifications/pyproject-toml/#dependencies-optional-dependencies
I guess we’ll have to deal with these idiosyncracies as well :(
