Bug introduced by
This use statement conflicts with another class in this namespace, Meanbee\MagentoRoyalmail\Model\Method.

Let’s assume that you have a directory layout like this:

.
|-- OtherDir
|   |-- Bar.php
|   `-- Foo.php
`-- SomeDir
    `-- Foo.php

and let’s assume the following content of Bar.php:

// Bar.php
namespace OtherDir;

use SomeDir\Foo; // This now conflicts the class OtherDir\Foo

If both files OtherDir/Foo.php and SomeDir/Foo.php are loaded in the same runtime, you will see a PHP error such as the following:

PHP Fatal error:  Cannot use SomeDir\Foo as Foo because the name is already in use in OtherDir/Foo.php

However, as OtherDir/Foo.php does not necessarily have to be loaded and the error is only triggered if it is loaded before OtherDir/Bar.php, this problem might go unnoticed for a while. In order to prevent this error from surfacing, you must import the namespace with a different alias:

// Bar.php
namespace OtherDir;

use SomeDir\Foo as SomeDirFoo; // There is no conflict anymore.

Bug introduced by
It seems like $this->getConfigData('rounding_rule') targeting Magento\Shipping\Model\C...arrier::getConfigData() can also be of type false or null; however, Meanbee\MagentoRoyalmail\Model\Rounder::round() does only seem to accept string, maybe add an additional type check?

This check looks at variables that are passed out again to other methods.

If the outgoing method call has stricter type requirements than the method itself, an issue is raised.

An additional type check may prevent trouble.
