If these issues can only be solved through experiments, why not 
experiment? Since D 2.0 is a development branch now anyway, it could 
have a switch that enables const-by-default. A few months later we'll 
know more...
Correct me if i'm wrong, but my understanding is that the CbD feature 
itself is easily implemented in the compiler. Therefore this shouldn't 
lead to a lot of potentially lost work.
