Pretty big rush to judgement. Slice off a copy of the arguments if you need them, but

  pall = -> console.log line for line in arguments; return

would have done just fine there.

One can be annoyed by `return` in tail position, or delighted by invocations-as-expressions. But not both. It's ok to choose the latter. :-)

Also, `console.log` is not a fit for map, forEach, et al. Check the parameters.
