> The current parser is limiting the forall() CE, not allowing nested "from" CEs. 
> E.g. Given the classes:
> ExpenseReport{
>   Collection<ExpenseDetails> expenseDetails
> }
> ExpenseDetails{     \
>   ExpenseReport document
>   ExpenseType expenseType
> } 
> it is not possible to write the following rule:
> rule "Do Not Process TAX"                       
>  when
>                $report: ExpenseReport($expenseDetails: expenseDetails)
>                forall ( ExpenseDetails( expenseType == ExpenseType.TAX ) from $expenseDetails )
>  then
>                System.out.println("################ It works ##################");
> end
