31 Each macro knows its name and included text. It gets built with a
32 list of formal arguments, and also keeps a hash table which points
33 into the list to speed up formal search. Each formal knows its
34 name and its default value. Each time the macro is expanded, the
47eebc20 35 formals get the actual values attached to them. */
