## Summary Closes: https://github.com/astral-sh/ty/issues/551 This PR adds support for step 4 of the overload call evaluation algorithm which states that: > If the argument list is compatible with two or more overloads, determine whether one or more of the overloads has a variadic parameter (either `*args` or `**kwargs`) that maps to a corresponding argument that supplies an indeterminate number of positional or keyword arguments. If so, eliminate overloads that do not have a variadic parameter. And, with that, the overload call evaluation algorithm has been implemented completely end to end as stated in the typing spec. ## Test Plan Expand the overload call test suite.
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.
