Well D has already taken the piss on that talk a long time ago.

No offense to D overall, and I still love it.


Rumours that Ali's next book will be called "Effective D++" 
are. true ;-)

So that:
```D
const int* ptr;
auto p2 = ptr;
static assert(is(typeof(p2) == const(int)*));
```

I really can't think of any downside to it, only upsides:
- It is still predictable / consistent;
- It *might* reduce the number of template instantiations in 
some cases;
- It just flows more naturally... If you want full constness, 
there's still `const`;


It sounds sensible to me.
