Ah, yes, I should have phrased it to make it clear I didn't have 
that kind of thing in mind.

In your example we are in the realm of "well, you promised 
something and then you didn't follow through, and this is 
@system, so you're on your own". Whereas things like evaluation 
order, alignment, etc. could arguably all be specified such that 
D does the right thing, even in various cases where in C they 
would be undefined behavior.
