## Summary Use the declared type of variables as type context for the RHS of assignment expressions, e.g., ```py x: list[int | str] x = [1] reveal_type(x) # revealed: list[int | str] ```
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.
