The main issue isn't the scoping, the main issue will be the missing implicit conversion to underlying_type.In few cases the implicit conversion to underlying_type is kind of important.Especially in the cases where the api has int and is mostly used with enums or is somehow user extendable. Qt::ItemDataRole is one of them that comes to mind. switch(role) { case Qt::UserRole+1: .... QEvent::Type is another one where one registerEventType, recieves an int and then force-cast it to QEvent::Type and still compares back to that int in other places. There are definitely more.
There's little reason why registerEventType returns `int` and not QEvent::Type, by the way. Model roles could become scoped enumerations, which can be explicitly constructed from integers (all of this just to retain the switch()-ability -- otherwise a model role should be represented by a wrapper type around integers. Certainly not be kept as a plain int).
