Except in my experience (and others as well) the tree shaking hasn't been working.

  Strange, I have it working with rc3. I have an ES6 module exporting tons of Array utils. I definitely see the build size fluctuate depending on whether I import 1, 2, etc of these util functions, whether with webpack 1 (or most bundling tool apart from rollup) I would pay the entire file's price upfront.

  The problem with tree-shaking is that it's recursive -- every module has to do it properly, and at the moment, I'd wager most frontend modules in NPM don't. If I responsibly say `import { map } from 'lodash'`;, but (say) my frontend rendering library says `import _ from 'lodash'; _.map(things, func);`, then unfortunately, transitively, I'll still get all of lodash.

    You might be able to fix that with something like babel-plugin-lodash which can be ran over your code (and deps) to enforce cherry-picking across the board. https://github.com/lodash/babel-plugin-lodash https://github.com/lodash/babel-plugin-lodash

      Late reply, but, neat! I'll have a look.
