Subject: | Avoid Guard or make it at least optional |
Since https://metacpan.org/release/Guard has no reasonable license nor any terms of use pointing to a reasonable statement of the author regarding the permissions of using his code, it's an unpredictable risk for any consultant/employee to use such a software in any product.
Please work out and document where Guard is needed and make it optional (recommended) if it cannot be avoided at all and add documentation how to avoid it.
