in reply to How Constant pragma works with multi constants

Can you please tell me what is structure of anonymous hash (without name) is stored in Symbol Table how Perl decodes the value here

use constant { STRAIGHT_LINE_ID => 1, PRORATED_ID => 2, CBP_CUSTOM_ID => 3};

Here the anonymous has not any name

If the code is written like below then I can say the value can be fetched from memory with perticular name

use constant TICKET_FIELDS => qw(ticket_id date_modified date_created ); my %ticket_fields = map {$_=>1} TICKET_FIELDS;

Please correct me whether I am wrong to store a anything in memory a variable is needed, and anonymous hash itself a memory and without name. How the value is fetched?

    You are replying to yourself. Moreover, the answer to the question has already been given: The anonymous hash is used as a parameter to constant::import, which can easilly access it in its @_.
