You always know the current static type locally. Sure one might need this in some generic function to extract the static type from an instance, but most of the time we could just write <code>T.self</code> to do that.</p>
<p>If there really is a need for that function, we could move it to future talk when might want to add the following function to the language.</p>
<pre><code class="swift">/// This function could find dynamically metatypes if they exist (even value types).
func type/subtype<T>(of type: Type<T>, named name: String) -> AnyType<T>? { … }
protocol P { init() }
struct S : P { init() {} }
let struct: P = subtype(of: P.self, named: "S")!.init() // Neat
struct is S //=> true
// One day when `.self` magic is removed, we'd have this nice form.
let struct: P = subtype(of: P, named: "S")!.init() // Neat
// With the proposed metatype model we could even get the static metatypes for protocols
let protocolMetatype: AnyType<Any> = subtype(of: Any.self, named: "P")!
protocolMetatype is Type<P> //=> true
protocolMetatype is AnyType<P> //=> false
</code></pre>
<p>Again this is something for the future, but I felt like I had to mention it.</p>
<hr>
<p>I’ll fix the typo, thanks.</p>
