If a Java program has to do the same work as "the same" program in C++, 
and _additionally_ run a VM, do JIT compiling -- I can't see how it's 
even theoretically possible to "reach C/C++ speed".

Oh well, I guess it's everybody's constitutional right to claim to 
become one day "as fast" as C/C++. I've heard that claim ever since many 
here weren't even born.

This is one of the places D should claim and occupy, Java on steroids or 
not. In other words, what would Java do if D's libraries and tools 
suddenly got equal to Java's?
