* A number of steps could be taken to increase the performance of
the optimized code. These include:
1. Switching the generated code to use the new ZVal-related interfaces.
1. Switching the generated code to use the new ZVal-related interfaces, including for vector operations.
2. Directly calling BiFs rather than using the `Invoke()` method to do so. This relates to the broader question of switching BiFs to be based on a notion of "inlined C++" code in Zeek functions, rather than using the standalone `bifcl` BiF compiler.
3. Switching the Event Engine over to queuing events with `ZVal` arguments rather than `ValPtr` arguments.
4. Making the compiler aware of certain BiFs that can be directly inlined (e.g., `network_time()`), a technique employed effectively by the ZAM compiler.
