/// tip

You can use `async` or regular functions.

**FastAPI** will do the right thing with each, the same as with normal dependencies.

## A dependency with `yield` and `try` { #a-dependency-with-yield-and-try }

If you use a `try` block in a dependency with `yield`, you'll receive any exception that was thrown when using the dependency.

We are still using the same `OAuth2PasswordRequestForm`. It includes a property `scopes` with a `list` of `str`, with each scope it received in the request.

- **5-15% faster** type conversions with pattern matching and switch expressions
- **Reduced memory allocation** in collection operations and bean copying
- **Improved reflection performance** with cached descriptors and optimized field access
- **Enhanced collection operations** with Java 21 sequenced collections support
