**Do you want to request a _feature_ or report a _bug_?** bug **What is the current behavior?** In #8027 some [example](http://react-new-docs-temporary-preview.surge.sh/react/docs/lists-and-keys.html#extracting-components-with-keys)s use `Number` as component name ``` javascript function Number(props) { // ... } ``` Maybe it is a good idea to rename this component to `NumberItem` or something.
