Nested loops on same variable (may) cause inifinite redraws

[narenranjit]

<div data-f-foreach="somearray">
   .. stuff --
   <div data-f-foreach="somearray"> </div>
</div>

This seems to cause a loop of constant updates as the 'child' asking for the same data as the parent triggers the parent to redraw.

Fix by implementing something like shouldComponentUpdate from React (compare data before re-rendering).
