Can I leverage interceptors to intercept lock calls?

[julealgon]

The interceptors feature can only intercept methods, which would mean it wouldn't be possible to intercept a reserved keyword call like lock. However, lock is transformed by the compiler into a pair of Monitor.Enter and Monitor.Exit calls on a try/finally block.

Would it then be possible to intercept these underlying transformed calls using interceptors?

For context, I'd like to add telemetry information every time a lock is acquired or exited, and interceptors would allow me to do that without touching the original code to replace it with a custom wrapper lock class.
