| 34 | Each macro knows its name and included text. It gets built with a | |
| 35 | list of formal arguments, and also keeps a hash table which points | |
| 36 | into the list to speed up formal search. Each formal knows its | |
| 37 | name and its default value. Each time the macro is expanded, the | |
| 47eebc20 | 38 | formals get the actual values attached to them. */ |
