  Previously _magic_ `multi`:

  ```elixir
  project %AnEvent{name: name}, _metadata do
    Ecto.Multi.insert(multi, :example_projection, %ExampleProjection{name: name})
  end
  ```

  Now `multi` is provided as a argument to the project function:

  ```elixir
  project %AnEvent{name: name}, _metadata, fn multi ->
    Ecto.Multi.insert(multi, :example_projection, %ExampleProjection{name: name})
  end
  ```

  The previous `do` block approach is still supported, but has been deprecated. It will be removed in the next release.
