static mostly comes from C++.
The only one of those D added that isn't natural and consistent 
is enum for manifest constant. I grant you some leeway for the 
unary `is` type check, but it still seems a natural extension 
from the binary form. (It is easy to read and understand).

If you compare the spec for the subset of D which C++ can 
implement, I think you will find it is more complex than the spec 
for D. References and lambdas for example.

When designing a language, minimizing the set of keywords is not 
necessarily a good goal, the opposite is often true. You want 
code to look obvious. There are often tricks to reuse keywords, 
I'm glad D generally doesn't do that.
