Higher order function is a functional pattern. In some OOP languages where functions were not available (Java7), it was not possible to create Higher order function without classes. https://en.wikipedia.org/wiki/Higher-order_function

In fact, render as props is more an OOP pattern. You pass render functions as props and you use delegation pattern to pass context. https://en.wikipedia.org/wiki/Delegation_pattern

ReactTrainig maybe should fix react-router-redux to work with redux time travel.
