I defined a custom type:

type alias Props =
  { user: SafeUser
  , onEdit: Signal.Address String
  , products: List Product
  , flash: String
  }

And a function using that type:

view : Props -> Html
view props =
	…

And then I called it with a type, but missing an attribute:

view {user = …, onEdit = …, products = …}

I had this situation, but Elm compiled fine. In the runtime, the code using “flash” rendered with a value of “undefined”
