RE: [sv-bc] RE: [sv-ec] Query for Iterator index querying

arr is an unpacked array.
 
item is the iterator, iterating over the elements of arr, each of type
int.
 
item.index is its index.
 
q is a list of those elements (items) whose value (item) is equal to its
index (item.index).

	But according to the example mentioned in SV LRM(sec 5.15.4),
item is not an unpacked array.
	So is the following testcase is valid one? 
	
	testcase:
	-------
	int arr[] ;
	int q[$]; 
	 q = arr.find with ( item == item.index ); 
	
	If it is valid then what is the value of item.index?
	What is the difference between item.index(1) and item.index?
	Another question is  whether iterator can be an unpacked array
as here item is treated as iterator?
	
	
	Thanks,
	
	Moumita

			Hello,
			
			 IEEE std 1800-2005 standard for System
Verilog,sec 5.15.4  
			does not say anything about the array for index
method ,so my 
			query is whether index method (Iterator index
querying) can 
			be applied  to unpacked array or packed array?
			If we have -
			q = arr.find with ( item == item.index );  //
item is packed 
			array or unpacked array?
			
			Also the language "The index method of an
iterator returns 
			the index value of the specified dimension." is
not clear to me.
			So for the following testcase what will be value
of x?
			 bit i[2:0];
			    int x;
			    initial begin
			        x = i.index();  
			    end
			
			Thanks and regards,
			
			Moumita
