## Summary Infer the first argument `type` inside `Annotated[type, …]` as a type expression. This allows us to support stringified annotations inside `Annotated`. ## Ecosystem * The removed diagnostic on `prefect` shows that we now understand the `State.data` type annotation in `src/prefect/client/schemas/objects.py:230`, which uses a stringified annotation in `Annoated`. The other diagnostics are downstream changes that result from this, it seems to be a commonly used data type. * `artigraph` does something like `Annotated[cast(Any, field_info.annotation), *field_info.metadata]` which I'm not sure we need to allow? It's unfortunate since this is probably supported at runtime, but it seems reasonable that they need to add a `# type: ignore` for that. * `pydantic` uses something like `Annotated[(self.annotation, *self.metadata)]` but adds a `# type: ignore` ## Test Plan New Markdown test |

Markdown files within the mdtest/ subdirectory are tests of type inference and type checking;
executed by the tests/mdtest.rs integration test.
See crates/ty_test/README.md for documentation of this test format.
