At least, I can second that even with msvc variants, but perhaps Alan meant
-fpermissive or so.
I think implicit casts is *not* a good idea.

That would be a bit uglier in QML than a static or function type explicit
cast like in C++ unless there is a nice trick not to make map, object,
mapper function or so for enums with many values. Perhaps parseInt() or
something similar? I would not know.
If there is no nice trick, I would suggest allowing it (perhaps with a
warning on the console?) because I do not wish to maintain such code if I
know what I am doing. :)
