Not exactly.
A QStringRef points to an existing QString. Therefore, if we take a QString
that is pointing to a substring of an existing QString, the d-ptr is already
allocated. The new QString would be as cheap as the current QStringRef.
The issue we'll run into is that a substring could be "holding hostage" a huge
chunk of memory.
