This is close, but as someone already said, an index into a list just means you are mutating the list.

Your stable “identifier” needs to be a function, ie. a reused design pattern. Compared to the list, this would be an index function which gets an element from an arbitrary list, meaning you don’t have to mutate your list anymore, you just build a new one which still works with your function.

This is why languages which avoid mutation and side effects are always (to my knowledge) functional languages.

What I find mind blowing about the scale of the universe, is that on a logarithmic scale from the smallest possible thing to the largest possible thing, humans live at almost the exact centre.

He is like tony stark in a timeline where Tony stark decided to join the terrorists instead of building the suit to escape. Oh and in this timeline Tony Starks brain has been rotted away by ketamine

The second syntax isn’t actually enums at all, it’s closer to a union type definition. You can’t even define enum Colour = Red | Green | Blue using your second syntax.
