Oh, absolutely. I'm not at all claiming they are (Nor do I think others  
claim
that). It's just it was so hard to make you see the value of non-nullable
pointers, and I feared you'd regressed.

@disable this is awesome, really. And you're right that it's even better  
than
simple non-nullable pointers. Lastly, it's great that it's getting fixes.  
It's
been one of my favorite non-working features. :p

In a way, I fear that we'll end up like C++, with bare pointers/references
being considered experts-only and 'special use', and everyone will use  
smart
pointers instead.
