Hi, primary author of SDC here.
Existing compilers (DMD, LDC, GDC, DDMD) all descend directly
from the DMDFE. The DMDFE is thus the only real source of true
semantics of the language, except where directly contradicted by
Walter, Andrei, or TDPL. For the ecosystem to not become inbred,
a new front-end is needed.
Furthermore, like others, I have become frustrated at the various
bugs of the frontend. These bugs are passed on to all other
compilers because of the afore-mentioned ubiquity of the
front-end.
Lastly, I work on whatever interests me personally, not what
other people believe to be where my resources would be placed. I
do not need to defend myself to you.
