Does anyone know if googles V8 could benefit from being re-written (even partly) in D? I'm mostly a web programmer and only just started learning D, so I'm not real familiar with how these lower level languages work. It seems like C++ programmers openly admit that D is better than C++ in many ways, but because of the lack of documentation (which seems to be a little better as of late) it just isn't a viable solution for most projects.

I'd like to hear an unbiased opinion of whether D, assuming the proper docs were available, could replace the C++ code in V8, and if not, what exactly is holding it back?
