However, this implementation is far from ideal. In particular, if we start adding more and more data types to our events, we’ll have to remember to add fields to this CustomEventData struct and update all constructors. And differentiating between "typed" and "not-typed" events was important at first to understand the event system well, but it's a bit user-unfriendly in the long run.
Now that we’re more fluent with C# and type casting (especially thanks to our multiple glances at polymorphism and…
