Re: Non-null objects, the Null Object pattern, and T.init

Walter Bright:

I strong, strongly, disagree with the notion that critical 
systems should soldier on once they have entered an invalid 
state.

The idea is to design the language and its type system (and 
static analysis tools) to be able to reduce the frequency (or 
probability) of such invalid states, because many of them are 
removed while you write the program.
