This is, again, an example of what I was talking about earlier. I've never, ever 
seen this as an issue in 30 years of programming. There are plenty of problems 
that actually adversely affect programs one can work on. We don't need to spend 
time crafting solutions to problems that affect nobody.

It's like building a set for a movie. The set is meant to be seen only from the 
angle the camera is set up at. Any other angle and the set looks completely 
fake, and it being a facade is obvious. The reason is simple - there's no reason 
to waste time and money making it look real from any angle other than that of 
the camera.

The reason dmd checks for that (and not the former) is that such are actual 
problems that often appear in real code and bedevil programmers.

If you really want to be productive with this, rather than sitting back and 
thinking up imaginary problems, do things like peruse the bug database of a 
large open source project. Look for patterns of problems that might be headed 
off with language solutions.
