This PR implements a linter that warns when a deprecated coercion is applied. It also warns when the `Option` coercion or the `Subarray`-to-`Array` coercion is used in `Init` or `Std`. The linter is currently limited to `Coe` instances; `CoeFun` instances etc. are not considered. The linter works by collecting the `Coe` instance declaration names that are being expanded in `expandCoe?` and storing them in the info tree. The linter itself then analyzes the info tree and checks for banned or deprecated coercions. |
