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.
