Wow, can't believe it!

According to:
https://stackoverflow.com/a/14203288

all compilers LDC, GDC share a common frontend from DMD, so they 
all suffer from this?


And dmd itself is developed in D:
https://github.com/dlang/dmd
D 87.9%

by the best D-developers (authors & experts)! and who must 
believe D is one of the best OO language.

How come the DMD frontend is in such terrible state?
