I think the base pipe operator by itself is nothing but a win; I think it's pretty clear and unambiguous even if you aren't familiar with it, and it makes certain cases much more elegant. I don't really see any downsides to it, except maybe that it has limited usefulness on its own. My feelings about the "Hack pipe operator" are much more complicated. I can see how it dramatically expands the usecases for piping as a whole, given JavaScript's other norms and constraints (no automatic currying, lots of method calls). But I also think it tangles up control-flow in weird ways that could get really hairy fast. And at some point, when you're no longer "just piping" into a unary function, are you really gaining much benefit over the normal function call syntax?
