Elixir has it. To make it worthwhile, the entire standard library has to be designed to have the ‘object’ of the function as first argument.

   [1,2,3]
   |> Enum.map(&square/1)
   |> Enum.filter(&odd?/1)

Using a threading operator where there is no such consistency is painful. This is why I dislike CL’s or Python’s map function, taking the list to operate on as second argument, instead of first. A threading operator wouldn’t be as effective there.
