Learning D as main systems programming language

[Goran Petrevski]

I'm new in the programming, systems programming especially, but I 
want to learn D more as a systems programming language and by 
that I mean avoiding libraries at all. My goal is to write a 
simple operating system totaly in D (using Assembly wherever is 
needed) and by progressing in that project, learning this 
powerfull language as the main systems programming language. Any 
help/advice on this goal will be really helpful/appreciated. 
Thanks in advance.
