This allows users of builders to do things like:
dsl_state
|> Ash.Resource.Builder.add_new_action(:update, :publish,
changes: [
Ash.Resource.Builder.build_action_change(
Ash.Resource.Change.Builtins.set_attribute(:state, :published)
)
]
)If your builder function calls handle_nested_builders/2 with their input before building the thing its building.
