Create editable grid using a!forEach()

Question

Hi, 
 am converting all my editable grids from using a!applyComponents() to a!foreach(), What would be the approach for real time use case using for each. Let me know the syntax that would be helpfull. Please find the attached code which am using now. 
 rows: a!applyComponents(
function: rule!KSK_ruleToGenerateGrid(
items:ri!cdtPassedtoSaveValues,
index: _

),
array: if(or(isnull(ri!cdtPassedtoSaveValues), count(ri!cdtPassedtoSaveValues) < 1), {}, 1+enumerate(count(ri!cdtPassedtoSaveValues)))

)

Foreach makes looping more explicit very similar to Java. Loop thru an array and have the current item to work with instead of [index variable], last item, first item, index etc. The documentation has all the details 
 docs.appian.com/.../fnc_looping_a_foreach.html 
 
As far as an example look at this recipe: docs.appian.com/.../recipe_add_validations_to_an_inline_editable_grid.html

a!foreach supposedly improve performance. We have some editable grid using applyComponents and some using foreach I didn't notice much difference in performance.
