It is common practice to call |> as pipe (or pipeline operator) among
including ones that recently introduced it as an experimental feature.
Pipeline is a
common feature for functional programming, not just for "data pipeline."
(This blog post about the history of pipe operator might be
I agree this is a bit confusing for those who are familiar with other
but there's no other appropriate term to call |>.
