// MetaMethod and MetaProperty have both type names and actual ScopeTree types.
// When parsing the information from the relevant QML or qmltypes files, we only
// see the names and don't have a complete picture of the types, yet. In a second
// pass we typically fill in the types. The types may have multiple exported names
// and the the name property of MetaProperty and MetaMethod still carries some
// significance regarding which name was chosen to refer to the type. In a third
// pass we may further specify the type if the context provides additional information.
// The parent of an Item, for example, is typically not just a QtObject, but rather
// some other Item with custom properties.
