Provide Context.currentValue

Now that hooks have an easy, non-HOC, non-renderprop, way of accessing context:

const value = useContext(MyContext);

It’d be great to be able to do the same thing from class components, i.e.:

const value = MyContext.currentValue;

I know there would be caveats like “don’t capture the value” (b/c when the context value changes, you’d want to be sure you’re using the latest currentValue on each render), but hooks also have caveats about usage.

Cool, that sounds good. Thanks!

@bvaughn FWIW I have the start of this here: https://github.com/stephenh/rfcs/blob/add-context-current-value/text/0000-add-context-current-value.markdown

I just wrote the 1st draft; running it by a few people for edits/clarifications/etc., and then will submit a PR to the rfcs repo. Happy to have feedback before then on it, or just wait until the PR.

Thanks!
