I understand, and that's a drastic speed difference. But removing support for 
dmd can have the effect of balkanizing the D community. That's happened in the 
past, and it was terrible for all of us.

I have looked at:

I propose as a first step we can work towards eliminating the conditional 
compilation based on which compiler is running. Then we can look for low hanging 
fruit on the codegen to reduce the performance gap.
