## Summary This has been here for awhile (since our initial PEP 695 type alias support) but isn't really correct. The right-hand-side of a PEP 695 type alias is a distinct scope, and we don't mark it as an "eager" nested scope, so it automatically gets "deferred" resolution of names from outer scopes (just like a nested function). Thus it's redundant/unnecessary for us to use `DeferredExpressionState::Deferred` for resolving that RHS expression -- that's for deferring resolution of individual names within a scope. Using it here causes us to wrongly ignore applicable outer-scope narrowing. ## Test Plan Added mdtest that failed before this PR (the second snippet -- the first snippet always passed.) |

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.
