One of my draws to D was that it was a systems language that could be faster than something like Java.  I also was sick of C++ and its problems, such as code that requires workarounds for compiler bugs or lack of compiler optimization.  It's really sad to see D requiring the same kind of stuff.  For D to become as mainstream as C++, all of this stuff that bearophile posts must be fixed.

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.
