I hope the Linux Kernel won't ever become an example of how an NT 
micro-kernel shoudl be written..

Really? Let me point you to some of the famous threads by our Microsoft 
friends, including some of their most distinguished engineers:



     Larry: You said Macros work to hide the complexity and say so like
    it is a bad thing.. ? Excuse me but I thought that was the POINT of
    using a Macro..

Actually, in the world in which I live (writing systems programs that 
exist in the working set of hundreds of millions of users), hiding 
complexity is a very, very bad thing.

You need to be VERY careful whenever you do something that hides 
complexity, because it's likely to come back and bite you on the behind."

Also: "Rules of software engineering" touches on this:

> Seems like people who hate macros are the people who are drawn to reactos.

Seems like people who hate macros are the people who are drawn to NT, 
too. I'm glad 99.9% of the developers here are on that line of though.

Yeah, go tell Larry Osterman he's too stupid to learn a macro.

Read Larry's posts. Read them again. Read the comments by other MS 
engineers. If you still think hiding complexity is a good thing, God 
help you.
