Unfortunately, I have to take that back. C is faster than D even 
with compile-time regexes. I used the short running benchmarks 
first, where compile-time regex wins, probably because it saves 
some startup time. For large data, C is faster. It uses the regex 
engine from TCL. Maybe std.regex has just space for optimization?

I updated the benchmark results:
