When I complained about C++ safety to my C++ programmer 
colleague, he told me that the compiler just compiles what's 
written. On one hand I can understand what he wanted to say, but 
the wording is still hilarious and fits C++ very well. What I 
like in D is that if it's written doesn't mean that it will 
compile: invalid code should be rejected.
