send_list(+Ref, +Selector)

send_list(+Ref, +Selector, +Arg)

The utility predicate send_list/[2,3] is similar to send/[2,3], but any of the arguments may be a list. For each member of the Cartesian product a message is sent:

send_list([Box,Circle], pen, 2).

is equivalent to

send(Box, pen, 2),
send(Circle, pen, 2).

send_list/3 is often used to append menu items to a menu:

send_list(Menu, append,
              [ menu_item(quit, message(@arg1, free))
              , menu_item(hide, message(@arg1, hide))
              ]).
