David Peter c6ce52c29e [red-knot] Treat empty intersection as 'object', fix intersection simplification (#13880) ... ## Summary - Properly treat the empty intersection as being of type `object`. - Consequently, change the simplification method to explicitly add `Never` to the positive side of the intersection when collapsing a type such as `int & str` to `Never`, as opposed to just clearing both the positive and the negative side. - Minor code improvement in `bindings_ty`: use `peekable()` to check whether the iterator over constraints is empty, instead of handling first and subsequent elements separately. fixes #13870 ## Test Plan - New unit tests for `IntersectionBuilder` to make sure the empty intersection represents `object`. - Markdown-based regression test for the original issue in #13870		2024-10-22 21:02:46 +02:00
