Real world example does not work on master

[headquarters]

1. Clone the repo on the master branch
2. cd redux/examples/real-world
3. npm install
4. npm start

The real world example fails with the following errors:

./src/containers/App.js
  Line 9:   'propTypes' is not defined           no-undef
  Line 18:  'handleDismissClick' is not defined  no-undef
  Line 23:  'handleChange' is not defined        no-undef

If I pin all the dependencies to the exact version in examples/real-world/package.json, do another npm install, and try again I get similar errors but only reported for UserPage.js.

So this appears to be an issue with the class properties transform not working properly, but I couldn't pinpoint the exact cause. If I figure out a solution I'll put up a PR.

Those do not appear to be "real" errors, but rather ESLint warnings that are being marked as errors. I think CRA may have somewhat recently decided to enforce some ESLint rules as errors.

Not sure on the right way to take care of this.

Ok, that makes a lot more sense considering everything is actually defined that is reported. When linter errors take over the screen and don't let you actually see the app, though, I still consider them "real". 😄

How about a PR to disable those with /* eslint */ rules in those files?

Some extra information: the example works if you do NOT do yarn or npm install at the top level of the redux repo.

So, if you only install the modules in examples/real-world, it works. If you go up to the root redux folder, install the modules, then go back and reinstall in real-world and re-run the example app then these errors show up.

Huh. That's... interesting. Some side effect of ESLint config resolution, I guess?
