## Future

By this point, it's already clear that **FastAPI** with its ideas is being useful for many people.

It is being chosen over previous alternatives for suiting many use cases better.

Many developers and teams already depend on **FastAPI** for their projects (including me and my team).

But still, there are many improvements and features to come.

### Reflection

- [`KT-47973`](https://youtrack.jetbrains.com/issue/KT-47973) Reflection: "IllegalArgumentException: argument type mismatch" when using callSuspend to call a function returning value class over primitive
- [`KT-41373`](https://youtrack.jetbrains.com/issue/KT-41373) "KotlinReflectionInternalError: Unresolved class" when inspecting anonymous Java class

 *  Fix: Don't crash when a fast fallback call has both a deferred connection and a held connection.
 *  Fix: `OkHttpClient` no longer implements `Cloneable`. It never should have; the class is
    immutable. This is left over from OkHttp 2.x (!) when that class was mutable. We're using the
    5.x upgrade as an opportunity to remove very obsolete APIs.
 *  Fix: Recover gracefully when Android's `NativeCrypto` crashes with `"ssl == null"`. This occurs

This will be especially useful when you use it in a **large code base** where you use **the same dependencies** over and over again in **many *path operations***.

## To `async` or not to `async`

As dependencies will also be called by **FastAPI** (the same as your *path operation functions*), the same rules apply while defining your functions.

**Network Interceptors**

 * Able to operate on intermediate responses like redirects and retries.
 * Not invoked for cached responses that short-circuit the network.
 * Observe the data just as it will be transmitted over the network.
 * Access to the `Connection` that carries the request.
