Babili no longer working with webpack 3.0.0

[bradennapier]

As of webpack 3 this appears to no longer work. I thought it was a few other things but I have narrowed it down to babili breaking arg spreading.

I have updated everything to the latest.

const r = Object.keys(selected).reduce((...args) => {
    console.log(args.length); // 4
    handleProcessReduction(selected, ...args);
  }, {});

function handleProcessReduction(selected, ...args) {
  console.log('p: ', args.length); // 1
} 

I can see it is not doing the right thing:

return Object.keys(e).reduce(function() {
            for (var r = arguments.length, t = Array(r), n = 0; n < r; n++)
              t[n] = arguments[n];
            console.log(t.length), u.apply(void 0, [e, t]); // [e, t] not [e].concat(t)?
          }, {});

My babel config is just default

babel: {
    plugins: ['transform-class-properties'],
    presets: [
      'stage-0',
      [
        'env',
        {
          modules: false,
        },
      ],
    ],
    env: {
      production: {
        presets: ['babili'],
      },
      test: {
        plugins: ['istanbul'],
        sourceMaps: 'inline',
      },
    },
  },

It works perfectly in the reply which adds to the annoyance here haha

I'm sure it's something stupid I am doing but I can't imagine what - this is an extremely simple setup.

Switching to uglify fixes this:

return Object.keys(e).reduce(function() {
            for (var r = arguments.length, t = Array(r), n = 0; n < r; n++)
              t[n] = arguments[n];
            return console.log(
              'reduction: ',
              t,
              t.length,
            ), u.apply(void 0, [e].concat(t));
          }, {});

Yeah, this one has been biting a lot of people—it's fixed on master by #578, but not yet released!
