The error message for bare lambda expressions (e.g., `x -> y`) was fixed in PR PRQL#5634. Move the test from bad_error_messages.rs to error_messages.rs since the error is now clear and helpful. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
