I'm really not a fan of the function bind operator. It adds extra complexity to the meaning of "this" in JS, which is already one of the most confusing aspects of the language.

I do understand that it is nice to be able to write those chained method call pipelines, without having to monkey patch anything. I think the |> operator from Elixer is a much simpler solution to this problem through, as it allows you to use normal functions, rather than having to write special versions that use 'this' for their primary data.
