> cqlsh:test> INSERT INTO cas_update (id, name , friends ) VALUES ( 10,'John',['Paul','George']);

> ----+--------------------+------
> 10 | ['Paul', 'George'] | John
> cqlsh:test> UPDATE cas_update SET friends[0]='Helen' WHERE id=10 IF name='John';
> Bad Request: List index 0 out of bound, list has size 0

> It seems that we cannot update list element by index with a CAS condition.
