functor

The functor option allows you to make your flake callable.

If it is set to a function, that function will be set as the __functor attribute of your flake outputs.

Conflake uses it so that calling your conflake input calls conflake.lib.mkOutputs.

Usage

As an example:

{
  inputs.conflake.url = "github:ratson/conflake";
  outputs = { conflake, ... }:
    conflake ./. {
      outputs.testvalue = 5;
      functor = self: x: x + self.testvalue;
    }
}

With the above flake, another flake that has imports it with the name addFive would be able to call addFive 4 to get 9.
