Oh, and I vote no. I think it's needless complexity. I code without any 
special care for null objects, and I get a segfault or 
NullReferenceException maybe once a week, probably less. I've always 
been able to track down the bug very quickly.

Having types be non-nullable by default would harm my productivity a 
fair bit. Having them be optionally non-nullable would be okay, as long 
as the libraries I use don't use non-nullable types.
