Example within documentations of D seriously need some improvement.

I remember if I am not wrong, C++ can do operator overloading and also 
overriding operator that also at child class. Sounded cool, but the more...
you heard that before haven't you... :)

 >closures yet
Semi-correct, Not within the standard syntax. But available also.

Does D have? Perhaps someone may give some URL

http://en.wikipedia.org/wiki/Inversion_of_control
Along side with spring framework?? That allow classes to be late binded 
via configuration in xml file.

Implementation techniques
    1. using a factory pattern
    2. using a service locator pattern
    3. using a constructor injection
    4. using a setter injection
    5. using an interface injection
    6. using a contextualized lookup

http://en.wikipedia.org/wiki/Aspect-oriented_programming
using http://en.wikipedia.org/wiki/AspectJ

There are many many extension because I think the bytecode allow such 
manipulations and not limited to the standard syntax of Java.

Perhaps something similar can be done with the Object file in D. :)

Yes... I am still a coffee(Java) addict. Sorry cannot stop that. Addict.
May need to take some 12 steps program... :)
