But _what_ does it break? The lack of logical const is definitely limiting, 
but at the moment, I can't think of even one case where transitive const is a 
big isue. The only issues with const that I can think of (aside from quality 
of implementation issues with the current compiler) are the lack of logical 
const and the issues with having a non-const reference to a const object 
(which Rebindable fixes and Michel Fortin's propose language change would do 
an even better job of fixing if it ever gets accepted). You seem to have an 
issue specifically with the transitivity of const, and I don't understand what 
the problems are that transitive const is causing.
