Components are not pure

[cerisier]

First, Thanks for the awesome work.

Even tho the components you've written are all stateless components, they are still not treated as pure by React; which means that React will re-render them all even tho their props did not change.

See facebook/react#5677

I understand that Layout components like Container, Box should not behave this way otherwise child components would not be rendered at all. but leaf components such as Button etc would benefit from it ?

On way we could get around this here would be to implement the shouldComponentUpdate method and do a shallowCompare of the props.

Closing this actually as benefits would be hardly visible after a second thought...
