How to import flakeModules provided by other partitions

[brsvh]

When I try to use flakeModules provided by another partition B in partition A, I don't know how to continue.

For example, a flake like this:

{
  inputs.flake-parts = "github:hercules-ci/flake-parts";

  outputs = inputs@{ flake-parts, ... }: flake-parts.lib.mkFlake { inherit inputs; } {
     imports = [
       flake-parts.flakeModules.partitions
     ];

     partitionedAttrs.flakeModules = "bar";

     partitions = {
        foo = {
          module = { ... }: {
            #           ^ Should I use `self' here? It seems to refer to `inputs.self' of foo.
            imports = [
               # How to import a flakeModule provided by `bar'.
            ];
          };
        };
        bar = ...;
     };
  };
}

bar/flake-module.nix

{
  flake.flakeModules.baz = ./baz.nix;
}

Haven't tried yet, but imports = [ self.flakeModules.baz ]; should work.
self is an argument to the outputs function, and also a module argument, in case you're doing this in a separate file.
