What is the current behavior?
Currently if we by mistake pass a JS object to JSX instead of a string, then we get the following error:
"Error: Objects are not valid as a React child (found: object with keys.."

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://jsfiddle.net or similar (template: https://jsfiddle.net/84v837e9/).

What is the expected behavior?

Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?

Can you propose a specific wording that would be better?

We haven't heard many complaints about this error, and the wording is straightforward. Plus, it gives you a list of keys and a component stack trace so I think this is clear enough, unless we here more specific feedback about it.
