Ok, maybe it's a matter of taste and opinion, but I consider them to be bad design (idea-wise, not implementation-wise) because they're sort of the opposite of DbI and compile-time duck-typing. Maybe they fit nicely in Rust's world but they're definitely something I would want NOT to use. Concepts/traits are useless when you have DbI, because you can implement them in a library if you need dynamic dispatch (e.g. std.range.InputRangeObject, std.experimental.allocator.allocatorObject, std.typecons.wrap, etc.).
Can you demonstrate it through the example you linked to? And sorry, what's DbI again? :D
