Right now we have the unfortunate situation where pipe last and pipe first modules are all together under Js, e.g. Js.String is pipe last and Js.String2 is pipe first. We could add Js.DataFirst modules that allow you to use pipe first operators while the standard Js modules support pipe last operator as they always have. In your program you can specify your preference for pipe first by adding open Js.DataFirst; to the top of a source file or -open Js.DataFirst in dune file.

This is analagous to StdLabels which allows you to easily swap out normal List functions with versions that use labeled arguments.
