Allow passing context assigns to slot content about surface HOT 2 CLOSED

Hi @mathewdgardner!

<slot/> is translated to the anonymous function @inner_content.() and as such, can only access variables (consequently the context) that belong to the same scope where it was defined. So you need to either move Parent.ContextProvider out of Parent and place it explicitly as a parent of Child or pass whatever you need using <slot :props={{ some_prop: value }}/> and then retrieve it using :let={{ some_prop: var }}.

I'm currently working on the documentation of the slots API, where I explain how :props and :let works. I should release the new docs by the end of the week. In the meantime, in case you need to see how it works, you can take a look at slot_test.exs. There are many tests using :props and :let.

Thank you @msaraiva for your clarification.

I can move the context into the parent but I need the child to be able to get updates to it. Is there any mechanism for a child getting context from the parent updating or re-rendering?
