If we are going to introduce dream2nix, why not poetry2nix, too? How would you compare dream2nix with poetry2nix?

[aareman]

Looks like dream2nix is a generalized form of all the X2nix tools.

I see this is being implemented as part of the Python module. Given the design of dream2nix, isn't it better to have its module, so it can be used with other languages?

[DavHau]

Yes, I was also thinking about a more generic approach. Maybe I'll have another shot at it some time.
