rewrite rendering context

Thoughts on rewriting the rendering context module

consider a basic element: Foo(params) { child1, ..., childn }

this translates to

React.createElement(Foos-react-class, params, result-of-eval-of-child1 .. result-of-eval-of-childn)

now each child is in turn either just another element, so each of those results-of-eval-of-child is just another createElement
