Hello @smilingprogrammer
To understand this feature better it is useful to add a simple example here: https://github.com/hyperactive-project/Hyperactive/tree/main/examples
It is also important to add some simple tests to cover this feature. To inform users of this feature we also need a section in the docs: https://github.com/hyperactive-project/Hyperactive/tree/main/docs/source
