Official compiler

[Dejan Lekic via Digitalmars-d]

Lots of programmers out there use and love languages that are far 
slower than any code DMD produces (think JavaScript, Python, 
Ruby). So I see no point here. If someone is learning D, and they 
know there are different compilers available, they would find out 
what are the differences. OpenJDK's JVM is not the best JVM in 
the world, yet millions of people use it.

What I find in having DMD being a *reference compiler* useful is 
to have a compiler which has latest language changes.
