You can see that in the attached screenshot.
The example class shown in the screenshot can be found here

It should be considered to increase the refcount of functions that are passed
on to an external library at some point.
If this is not done and e.g. the function was a local variable, when leaving
the scope it gets garbage-collected. When the library now tries to
