instanceof doesn't work

This should be mentioned under “Limitations” in the readme. The work-around is to compare with the name property instead.

export default class ValidationError extends Error {
  constructor(invalidations) {
    super('Invalid input');
    this.invalidations = invalidations;
    this.name = 'ValidationError';
  }
}

try {
  throw new ValidationError(['message']);
} catch(error) {
  if (error instanceof ValidationError) {
    console.log('ok');
  } else {
    throw error;
  }
}

You know, I think my current project is not importing this library (due to https://github.com/facebookincubator/create-react-app/issues/2952) Even with it added locally to babel-preset-react-app, it doesn’t log “ok”.
