Hello, I was just thinking, If we're talking about collections, isn't it true that Objects themselves are essentially collections? If we use the slot metaphor...

They're not the same, no, but lazy evaluation makes it make some more sense. However, how do you message that object? You'd have to getSlot it, as though it...
