Yes, they believe they need it.  Sure.  But I doubt many of them have 
done any sort of analysis of how much it actually helps vs. how much it 
complicates their code base.  I say this as someone who was totally sold 
on C++ const for the first 10 years I used it.

Now I'm kind of used to not having it.  And, well, the sky hasn't 
fallen.  But lots of my code has lost superfluous redundancy.

But I'm going to start trying to compile my code with D2 this weekend 
and see how it goes.  Hopefully const will mostly stay out of my way.
