You already know how topics work in English, so we try to take advantage of that. You know how to express hypothetical ideas, so we'll try to take advantage of that too. You know how to explain something in terms of something else. That's how the classes and properties and traits are supposed to work together. Perl 6 will work more like a natural language than Perl 5, but it's still nowhere near the complexity of English or Japanese. Or Swahili, for that matter.
It seems to me that Perl 5 maps well onto, say, English, but now it seems like you're trying to map (parts of) Perl 6 onto something else ... a way of looking at things. I don't quite have the vocabulary to explain it, especially this late on a Saturday night, but it seems to me that this sort of a mapping is odd. Topics and hypothetical ideas? 2 + 2 might equal 4, but only when not driving a truck?
