Not usable on symfony/validator since syntax is broken on comment containing the word 'namespace'

[DevHiNet]

Tool erronously performs transformation also when the word 'namespace' is present in input files but has no syntactical meaning

Actually Symfony validation library contains a comment with the word 'namespace'

Original (untrasformed) source code

    [...]
    private \ReflectionClass $reflClass;

    public function __construct(string $class)
    {
        $this->name = $class;
        // class name without namespace
        if (false !== $nsSep = strrpos($class, '\\')) {
            $this->defaultGroup = substr($class, $nsSep + 1);
        } else {
            $this->defaultGroup = $class;
