I wanted this set of functions originally, though I never used any of those languages, so I suspect it's natural, I even implemented them in almost every project. That said now the |> &f(&1, a) syntax is so natural to me that I've since removed those functions. I don't think you can go *wrong* by adding it to the core lib, but you couldn't make me decide on a name with my job on the line.
