I do take your word for it, but now I have to re-evaluate my 
expectations towards D and perhaps use it for another project. 
I've got most of my project working in C already, but I was 
hoping to add some safety and better readability/managability by 
using some of the convenient features D offers over C. And, of 
course, learn D in the process. Also, your words give me the 
impression that I cannot trust the documentation; which isn't a 
great start into the learning process.

It can be evidence of something broken in D as you say 
(simplified) or of my lack of experience with D - a simple 
missing include, badly configured PATH, or lack of understanding 
on my part what SimpleDllMain does.
