@BlackSonic any idea why tree shaking doesn't work if the class extends React.Component?

Here's a simple reproduction:
cdeutsch@cc37b70#diff-f2a33497e4348acebe5f8fe829ffc6ffR19

Is it a bug with Babel-Minify?

Or are there side effects with extending React.Component?

As you can see V10 shows up in the prod bundle...

Also note, I upgraded your sample to use:

awesome-typescript-loader@3.2.3
babel-core@6.26.0
babel-minify-webpack-plugin@0.2.0
webpack@3.6.0
