Jerking people around with yet another non-working const regime would 
not help.

For example, the C++ const regime has massive backing from the C++ 
community. But it is fundamentally unsound. If you carefully monitor the 
email traffic of people working on C++0x, you'll see the problems, too. 
As programming shifts to more and more multiprogramming, and people get 
more and more fed up with programs that defy static verification, these 
unfixable problems will cause more and more people to abandon C++.

D needs to look to the future, and for that it needs a fundamentally 
(i.e. mathematically) sound foundation for const.
