Re: rest parameters

And defaults can have rest parameters afterwards. But yeah, I know it's convenient in a few cases, but I find myself in this situation rarely, so I'm not sure if it merits being in the spec. Also, the ES6 version isn't that much longer, and if a single `.pop()` becomes a bottleneck, there's

Re: rest parameters

I'm not trying to restart debate on this, but I do know CoffeeScript allows it. It does a greedy grab, but it only allows a single spread element, and default parameters take full precedence over rest parameters in what is taken. [1] As for optimization, that's probably the bigger issue. It's not

Re: Re: rest parameters
