render prop on <Form> seems missing

[gartner]

When working on upgrading from V3 to V4, I came across this in the upgrade guide:

• this explains that the arguments to the render() function has changed. However, it seems like the render() function is completely removed from the
  component. And that it instead uses child components.

Indeed, the form displays nothing when using the render() function, but works as expected when placing the contents as childs of

This is on the v4.0.0-rc.1

We noticed this behaviour as well, it looks like the new Form instead removes the need for renderProps, and the children should be rendered as regular React children. I think this may just need a documentation update?

It's a much neater pattern without the render props and required form element!

Edit: it's no substitute for documentation, but the source code provides usage examples. I hope this helps!

Hi! Thank you for submitting this. Indeed the doc needs to be updated on this point. I'll do a PR right away to fix this. Cheers
