There's an easier way. I suggest playing with an Altair 8800 
simulator. I don't recall what it does on things like division by 
zero, but in general it has the habit of just keeping going no 
matter how wrong your machine code is. It just won't do what you 
wanted and might well overwrite your code.

The utility of HLT instruction (or whatever it was, but it's the 
machine code equivalent of `assert(false)`) will be evident. 
Crashing is a feature, not a bug (but it is a response to a bug).

Also remember, D is designed by an airplane engineer. This means 
the program written in it *must* crash before the plane it could 
be flying does. Walter sure has refused to alter much lesser 
convictions of his than this one.
