I don't think anyone in particular is being blamed, but there is 
a mismatch between the chosen compiler architecture and an 
evolutionary development model. Evolution demands a more modular 
approach, and frankly, a constant reevaluation of the 
architecture with planned refactoring.

That's probably true for a lot of things, also things like 
[inconsistencies and limitations of 
alias]( probably started as a quick add-on, but there is a limit to how far you can go with just evolution. If one keeps on evolving without redesigning then one ends up painting oneself into a corner where completion becomes an intractable proposition.

The most sensible thing then is to start remodelling into layers 
where you have a chance. The obvious starting point is to put a 
layer between frontend and backend. But then you have to make it 
a priority. Projects like ```@live``` and ```importC``` are 
rather ambitious. For importC you basically need to do like clang 
and implement [the commonly used gcc 
Doing all of that at the same time pushes the finish-line far 
into the horizon. And then it is of limited use, even though a 
well developed ```@live``` analysis stage might be useful for 
analysing C-code and could possibly make some C-code accessible 
as ```@safe```.

Maybe D should do like C++ compilers and set up page with 
hatch-marks for feature completion. I don't start using next 
generation C++ or JavaScript without checking those feature 
tables for 100% completion.

For many contexts of serious software development having a 
half-baked feature is almost the same as not having it at all.
