argument (item count) of `GARY_PUSH` and `GARY_POP`. If you want to push/pop
multiple elements at once, use `GARY_PUSH_MULTI` and `GARY_POP_MULTI`.
* *Incompatible:* The interface of the <<heap:,heap>> module was cleaned up
- to remove non-systematic side-effects. The `HEAP_INSERT` operation is now
- a proper insert (previously, it was just cleanup after insertion performed
- by the caller), similarly `HEAP_INCREASE` and `HEAP_DECREASE`. The `HEAP_DELMIN`
- operation was renamed to `HEAP_DELETE_MIN`. New operations `HEAP_REPLACE` and
- `HEAP_REPLACE_MIN` have been added. If you need to track positions of elements
- in the heap, please check the notes at individual functions.
