I'm trying, really, to understand modern D features, but I'm from 
old school, C pure programming and BASIC language, and such 
languages and styles.

D as it's obvious to all of us is a multi-paradigm language and 
has so advanced features, even its references, I can't understand 
'em well, it's 100% new modern language, but every time I'll 
learn a new feature of it for that I can't surround all of its 
techniques at once.

Provide me a free solution better than code::blocks with 
available gdc compiler I found.
