I do not know about others, but I personally do not expect DMD to 
be as performant as people would like it to be. As a REFERENCE 
COMPILER I expect it to be as close to the current language 
specification as possible. DMD does that beautifully, and on top 
of that does a pretty good job at compiling code quite fast. I 
can't ask for more! - If they optimize the codegen to generate 
better code, that is fine, but not essential, as I use GCC 
(others may prefer LDC) for release builds.
