It looks like the examples are all still function calls. Could you 
clarify what expressions would be acceptable on the right-hand side?

In particular, can I assign to a variable at the end of the pipe?

foo() |> bar($$) |> $result = $$;

As discussed before, I think pipes would be most useful if values could 
"exit on the right". For which I would also like to be able to do this:

foo() |> bar($$) |> return $$;

(Or, as discussed, special syntax for one or both of these.)
