I also agree that cost is worth the effort.

Most of the roadblocks are relatively easy to overcome by rolling 
const-correctness through druntime and phobos.

However, I still regard the language design decision of a class 
reference having the same constness as the object it refers to as a 
major language design problem. I would be delighted if someone could 
point out to me how to neatly work around this though.
