Display Data from multi level collection

Just as a little example...

//Simple ForAll
CountRows(ForAll([1,2,3,4,5], Value)) = 5
First(ForAll([1,2,3,4,5], Value)).Value = 1
Last(ForAll([1,2,3,4,5], Value)).Value = 5

//ForAll to make records
CountRows(ForAll([1,2,3,4,5], {myVal:Value})) = 5
First(ForAll([1,2,3,4,5], {myVal:Value})).myVal = 1

//A little more structure
Last(
  First(
    ForAll([1,2,3,4,5], 
       {myVal:Value, 
        myTab:ForAll([10,20,30,40], Value)
       }
     )
   ).myTab).Value = 40

They're not all that complex to deal with, but one must remember...there are not For Next loops!!  They are data iterations.
