For now I saw:

Qt::Orientation:: => Qt::
QSizePolicy::Policy:: => QSizePolicy::
QLayout::SizeConstraint:: => QLayout::
Qt::AlignmentFlag:: => Qt::
Qt::TextInteractionFlag:: => Qt::
QDialogButtonBox::StandardButton:: => QDialogButtonBox::

But there are probably more. I think all enums containing a subspace
are suspicious. So we could probably test for Q*::*::* and at least
warn if such a case is found. 

Thanks,
