### namespace Literals::StringLiterals

The inline Qt::Literals::StringLiterals namespace declares literal operators for Qt string types. Because both `Literals` and `StringLiterals` namespaces are declared as inline, the symbols from this namespace can be accessed by adding one of the following to your code:

     // Makes visible only the literal operators declared in StringLiterals
     using namespace Qt::StringLiterals;
     // same, but needlessly verbose:
     using namespace Qt::Literals::StringLiterals;

     // Makes visible literal operators declared in all inline namespaces
     // inside Literals
     using namespace Qt::Literals;

     // Makes visible all symbols (including all literal operators) declared
     // in the Qt namespace
     using namespace Qt;

The latter is discouraged, because it doesn't allow you to pick which literal operators you want in case Qt adds conflicting operators in different namespaces within Qt::Literals.
