## Summary - Get rid of `Symbol::unwrap_or` (unclear semantics, not needed anymore) - Introduce `Type::call_dunder` - Emit new diagnostic for possibly-unbound `__iter__` methods - Better diagnostics for callables with possibly-unbound / possibly-non-callable `__call__` methods part of: #14022 closes #14016 ## Test Plan - Updated test for iterables with possibly-unbound `__iter__` methods. - New tests for callables
