Inherent code performance advantages of D over C?

When you have experience and you know how to do things, you have 
a great temptation of keep doing it, and limit your explorations 
and study of alternatives. But this could lead to missed 
opportunities and crystallization of skills. One strategy to 
avoid this pitfall is to allocate some time to learn different 
things, but often this is not enough. A way to improve the 
situation is to work for some time with a person aged very 
differently. Younger people seem ignorant, but teaching them for 
some time is not a waste of time because their age helps them 
being not burdened by very old ways of doing things, and they 
teach back you a lot.

Refactoring tools are an important part of modern programming. If 
you don't understand why, then I suggest you to stop debugging D 
for few days, install a modern IDE, find a good open source Java 
project on GitHub, and follow some tutorials that explain how to 
refactor Java code. In few days you could send some patches to 
the project and learn what modern IDEs do. It's even better if 
you find some younger person willing to work with you in this, 
but this is not essential :-)
