Chamfer and fillet are awesome, but the pipe… mixed feelings, especially since it uses a dash. Either a normal pipe or an Ocaml-like |> would feel more natural.
As for the syntax there are certainly a lot of ways it could feel. JS devs would likely be familiar with =>, F# and Ocaml |>, Java ->. In the end I just picked one that felt natural to type for myself. From my experience if you write in enough languages you develop the ability to switch as needed.
