Selecting from a list variable in PL/SQL

Why doesn't the initially remarked select work please?

DECLARE

TYPE table_list_type IS TABLE OF VARCHAR2(40);

v_table_names table_list_type;
v_table_name VARCHAR2(40);

v_pre_del_count NUMBER(8);
v_post_del_count NUMBER(8);

BEGIN

  v_table_names := table_list_type(
    'ACCOUNT_PERFORMANCE_DAILY',
    'CLIENT_PERFORMANCE_DAILY',
    'CORE_CASH_PERF_DAILY',
    'CORE_STOCK_PERF_DAILY',
    'SECTOR_PERFORMANCE_DAILY',
    'CORE_STOCK_PERF_DGROUPS',
    'CORE_CASH_PERF_DGROUPS',
    'CLIENT_PERFORMANCE_DGROUPS',
    'ACCOUNT_PERFORMANCE_DGROUPS',
    'SECTOR_PERFORMANCE_DGROUPS');

  FOR i IN v_table_names.FIRST..v_table_names.LAST
  LOOP 
    DBMS_OUTPUT.PUT_LINE( 'v_table_names(i) '||v_table_names(i) );
