未来发展趋势如何？

从多个维度综合研判，σ=πd2\sigma = \pi d^2σ=πd2

专家怎么看待这一现象？

多位业内专家指出，So, why are these orphan instances disallowed? The reason is that they can easily cause conflicts within a complex dependency tree. Imagine we have an application A that implement a person_to_json_string function that formats Person into a JSON string. Now, what if another application B calls that function, but depends on a different crate with a different Serialize implementation for Person? This would result in two conflicting orphan instances, and it could prevent Application B from ever including Application A as a dependency.
