* `const`s, that can be used in defining the size of tables, etc
* Remove the need for `forward` and `vector () table` (make grammar changes)
* Tests, and implementation, ensuring a routine can be assigned to a vector of "wider" type
* Check that the buffer being read or written to through pointer, appears in approporiate inputs or outputs set. * Check that the buffer being read or written to through pointer, appears in approporiate inputs or outputs set.
* `interrupt` routines -- to indicate that "the supervisor" has stored values on the stack, so we can trash them. * `interrupt` routines -- to indicate that "the supervisor" has stored values on the stack, so we can trash them.
