In fact, it might go hand-in-hand with changing how protection

Rather, you'll gain innumerably, thanks to every property/accessor now
being non-virtual as it should be.
You make a compelling argument, although I'm easily sold on sich matters!
It could be staggered in over a few releases... ie, in one release,
'virtual' is introduced - does nothing - encouraged to update code, next
release, complain that missing virtual is deprecated, next release, turn it
on proper; compile errors...
Walter would have a meltdown I think :P

Another reason I like the idea of a virtual keyword is that it

Hmm, this sounds familiar... where have I heard that before? ;)
