D being a systems language, you can without much difficulty do whatever works 
for you.

People do look to us for guidance, however.

The levels of programming mastery:

newbie: follow the rules because you're told to
master: follow the rules because you understand them
guru: break the rules because you understand their limitations

I'd be doing our users an injustice by not making sure they understand the rules 
before trying to break them.
