Yeah Interfaces would be the next best thing.

The only reason why traits are considered better is because in languages like rust it can enable static dispatch. Whereas interfaces in C#, Java, Typescript, (and C++ via abstract classes, not templates) are always dynamic dispatch.

At that point I would argue composition/traits are the way to go.

“This extends Draggable”. That’s great but now we can’t extend “Button” to override the click handler.

Traits: You wanna have Health, and do Damage, but don’t want to implement InventoryItem? No problem. You wanna be an Enemy and InventoryItem? Go for it. What’s this function take? Anything that implements InventoryItem + Consumable

It’s a shame because how gitlab is basically begging to be bought out and hides a lot of useful features behind subscriptions… I remember when it was originally just a GitHub clone way back when.

Rust was painful to look at until I started using it for more than 6 or so months
