        ]))
    };

maybe this would be a bit clearer?
(and allows for easier future mixing of all the other macro-rule options)

Suggestion:

    ($reason:expr) => {
        return Ok(SyscallResult::Failure(vec![Felt252::from_bytes_be_slice($reason)]))
    };
    ($existing:ident, $reason:expr) => {
        $existing.push(Felt252::from_bytes_be_slice($reason));
        return Ok(SyscallResult::Failure($existing))
    };
    ([$reason1:expr, $reason2:expr]) => {
        return Ok(SyscallResult::Failure(vec![
            Felt252::from_bytes_be_slice($reason1),
            Felt252::from_bytes_be_slice($reason2),
        ]))
    };
