Pipeline placeholder ^^ or %% or `|x>`

[crystalthoughts]

Hi, I think it would be a good idea to have the possiblity of aligning Civet more closely to the pipeline operator proposal (hack style). I think the only thing needed would be a configuration option to change something like: pp:= & |> (JSON.stringify ., null, 2) |> console.log to pp:= & |> (JSON.stringify ^^, null, 2) |> console.log

I also think it's a bit more readable. Any thoughts welcome :)
