Walter is the only one who can make DMD faster, and I think his time is much better spent on designing and maintaining the language. The reference compiler is just supposed to be _correct_, not necessarily _fast_. If Walter spent all his time working on making the the DMDFE optimizer better and making DMD backend produce faster code, he wouldn't have time to work on the language anymore, and it would be duplicated effort since GDC and LDC already do it better.
