If I'm reaching for this form, I'm likely thinking about a pipeline of unary functions, and the TC39 proposal seems to take the same approach. Plus, doesn't every other function in the pipeline need to be unary after the first?

As a half-baked thought, perhaps callPipe would take exactly one non-function argument to start the pipeline (which would appeal to most use cases), and applyPipe could take an array of args, mimicking the call/apply duality in native JS?
