Hello everybody,

I've been experimenting for a while with elm. Previously I tried plain elm
and I found it very effective to have a module for each sub-page of my
applications and a root module holding everything together.

I'm trying to follow the same approach with an app using elm-mdl but I
found this model is clashing a bit with the fact that elm-mdl requires to
pass an instance of Material.Model to some of the rendering function and
wants a custom message.

I’d normally have the classic `view : Model -> Html Message` function and
in the root module I’d put everything together doing `Html.App.map
MyPageMessage <| MyPage.view model.myPage`.

elm-mdl changes this a bit and it makes it hard to follow the same pattern.
I can make this work with a more convoluted view function but it feels less
clean than using `Html.App.map`. The signature of the view method on my
pages would be something like

view : Material.Model -> (Material.Msg a -> a) -> (Message -> a) -> Model
-> Html a

That way I can inject the mdl model, the constructor to create the
root-level messages (which include the MdlMessage).

I suspect there is a better approach but I'm struggling to find it.
What are the patterns you use with elm-mdl?

Thanks,
Mario
