    \class QmlFile
 
   A QmlFile, when loaded in a DomEnvironment that has the DomCreationOption::WithSemanticAnalysis,
   will be lazily constructed. That means that its member m_lazyMembers is uninitialized, and will
   only be populated when it is accessed (through a getter, a setter or the DomItem interface).
 
   The reason for the laziness is that the qqmljsscopes are created lazily and at the same time as
   the Dom QmlFile representations. So instead of eagerly generating all qqmljsscopes when
   constructing the Dom, the QmlFile itself becomes lazy and will only be populated on demand at
   the same time as the corresponding qqmljsscopes.
 
   The QDeferredFactory<QQmlJSScope> will, when the qqmljsscope is populated, take care of
   populating all fields of the QmlFile.
   Therefore, population of the QmlFile is done by populating the qqmljsscope.
