Handling infinite recursion

[TyberiusPrime]

When python packages depend on each other in a cycle,
we need to break the infinite recursion.

I had though this would work like poetry2nix,

        dark-matter = prev.dark-matter.overridePythonAttrs (
          old: {
            propagatedBuildInputs =
              removePackagesByName
              (builtins.trace (old.propagatedBuildInputs or []) (old.propagatedBuildInputs or []))
              (pkgs.lib.optionals (final ? gb2seq) [final.gb2seq]);
          }
        );

But at that point in the eval, propagatedBuildInputs is still empty, and therefore the recursion remains.

Perhaps you can shine some light on how to do this, @adisbladis ?
Thanks!
