* 2. Declare a typedef named my_cxt_t that is a structure that contains

* all the data that needs to be interpreter-local.
|
|
* 3. Use the START_MY_CXT macro after the declaration of my_cxt_t.
|
|
* 4. Use the MY_CXT_INIT macro such that it is called exactly once
|
|
* (typically put in the BOOT: section).
|
|
* 5. Use the members of the my_cxt_t structure everywhere as
|
|
* MY_CXT.member.
|
|
* 6. Use the dMY_CXT macro (a declaration) in all the functions that
