"relies on enormous amounts of mutability" of global state / 
variables?

Just curious: how DMD is becoming self hosted in D? it started 
from scratch, or being translated from the old C++ 
implementation? where this old mess baggage coming from?

I still feel puzzled:

D is supposed to be a better OO language (read: encapsulation, 
separation of concerns), and DMD is developed by a number of 
highly capable very experienced D developers (read: not ordinary 
programmers), how come DMD is in such a terrible state as if it's 
done by some average Joel (above)?

No offense, I am just puzzled by this software engineering myth.
