## Summary Ensure that we correctly infer calls such as `tuple((1, 2))`, `tuple(range(42))`, etc. Ensure that we emit errors on invalid calls such as `tuple[int, str]()`. ## Test Plan Mdtests
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.
