Here, we provide `pre` and `post` functions, which are executed before and after
`DemoClass::run`. The `pre` function starts and activates a span, and the `post`
function ends it. If an exception was thrown by `DemoClass::run()`, the `post`
function will record it, without affecting exception propagation.
In the example above we define `DemoClass`, then register `pre` and `post` hook
functions on its `run` method. The hook functions will run before and after each
execution of the `DemoClass::run()` method. The `pre` function starts and
activates a span, and the `post` function ends it.

If an exception was thrown by `DemoClass::run()`, the `post` function will
record it, without affecting exception propagation.
