Thanks for posting @BrendannnD.

We also use this pattern in the Tagged Lights Puzzle Tutorial.
For example, the button handler looks like:

 button_event_handler := class():
 # Positions used to access the lights this button controls.
 Indices : []int

 # tagged_lights_puzzle that created this button_event_handler so we can call functions on it.
 PuzzleDevice : tagged_lights_puzzle
    
 OnButtonPressed(Player : agent) : void =
     # Tell the PuzzleDevice to toggle the lights at the positions this button controls.
     PuzzleDevice.ToggleLights(Indices)
