Adding a feature specifically designed to bypass this seems unfortunate, especially since we already have an ugly feature (`arguments.length`) for doing such an ugly thing. On the other hand, Brendan's proposal seems pretty neat. I am pretty sure that while writing some Traceur code I wanted something similar. But even then, I suppose I would want `args` in his example to always have length `3`, so as to discourage the bad practice. I.e. `f(1)` would give `args` as `[1, undefined, undefined]`. It would be a way of reifying "arguments for the ES6 era," where differences between not-passed and `undefined` are minimized, and of course it would be a real array. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
