(Sufficiently sane) languages are not slow or fast and I think the 
factor GHC/DMD cannot be more than about 2 or 3 for roughly equivalently 
written imperative code.

Furthermore no D implementation has any kind of useful performance for 
lazy functional style D code.

In some ways, D is very significantly slower than Haskell. The compilers 
optimize specific coding styles better than others.

I disagree. That is certainly fixable. It is a mere QOI issue.
