Hi all, first post here (also a newbie in elixir/FP). So, I have next pipe code which works but also looks funny: case {status_code, body} do {200, _} -> edges = Poison.Parser.parse!(body) |> Map.get("data") |> Map.get("repository") |> Map.get("issues") …

Thanks a million guys! Working on your pointers. Any thoughts about question 2 (tee operator) ? Something like: data |> transformation_1 |> transformation_2 T> snapshot_data |> transformation_3 snapshot_data |> transformation_4

def f_1(data) do data |> transformation_1() |> transformation_2() |> f_2() end # still purely sequential - more like a (sequential) fork/join # because everything has to be an expression. # def f_2(snapshot_data) do {transformation_3(snapshot_data),transformation_4(snapshot_data)} # retur…
