| # Rustc by default uses the NLL borrow-checker. There are multiple cases where | |
| # NLL is too restrictive. An upcoming improvement to Rust's borrow-checker, | |
| # adressing these shortcomings, is Polonius. It ships with Nightly behind a | |
| # flag. | |
| # | |
| # This workflow first removes the workarounds necessary to please NLL and then | |
| # runs with Polonius to ensure each workaround only fixes the false-positive of | |
| # NLL and doesn't mask an actually undefined behavior. | |
