Subject: Does array's each-block destroies outer objects ?

Hi,

Please look:

> x = 2840
=> 2840
> x.object_id
=> 5681

> a = [1,2,3,4,5]
=> [1, 2, 3, 4, 5]
> a[4].object_id
=> 11


> a.each {|x| puts x}
1
2
3
4
5
=> [1, 2, 3, 4, 5]

>a[4].object_id
=> 11

> x.object_id
=> 11

After execute the block , it looks like that ruby destroied the former
'x' object, the 'x' object has object_id 4 now, which is same as
a[4].object_id.

If so , does it mean that I must choose another variable name in
array's each block to keep the 'x' object alive ?

Thank you.
