    The difference between "foo".bar().baz() and "foo" |> bar() |> baz() is not only syntactic. The former couples the name with the data.

        @josevalim conceptually is this closer to how Elixir pipes would look in Javascript?https://gist.github.com/jweir/9d51b0ad94fa270c95d2 …

        @josevalim The trick is to understand where OOP is useful, and where it's harmful. Pendulum is swinging, because we've been overusing OOP.

        @josevalim That said, I haven't gotten to the protocols part of the Elixir book yet. (Wish that part was earlier.)

        @josevalim 2. It allows easier specialization. The canonical example is shapes that need to be drawn differently.

        @josevalim 1. It avoids naming collisions. What if you have shapes you need to "draw", but you also need to "draw" a card from the deck?

        @josevalim Yes, but there are good reasons to couple the name with the data.

        @josevalim funny that you write this today. Just yesterday I thought on how to add pipeline to java and saw just this problem! FP FTW :)

        @josevalim @bryan_hunter Sure for JS/Java/etc, but where type classes exist (i.e. Rust), it's just syntax, yeah?
