Interesting. Read up on it and tried changing the strings to be 
~50 chars long. C++/std::string gets better, but C++/const char* 
still beats D by a small margin:

C: 1.852s
C++/std::string: 1.489s
C++/const char*: 1.034s
D: 1.188s

Could be the cost of swapping the "fat" in "fat pointer", in 
which case: worth it.
