I'm been thinking about using D in conjunction with C11 to 
develop a set of applications with hard real-time requirements. 
While initially the goal was to use C++ instead, it has become 
clear that D's introspection facilities will offer significant 
advantages. Unfortunately, the project will heavily rely on 
custom memory allocators written in C, so the presence of garbage 
collection in the language is a problem. While I'm aware that the 
nogc attribute exists, I haven't actually seen a way to apply it 
to a whole project. Is this possible?

Wonderful, i'll be looking into it. Thank you!

Do you want to write D code that just doesn't use the GC or the 
whole runtime?

If the former then use  nogc at the entry point of your D code 
(This means that - say - main cannot call anything non- nogc and 
therefore guarantees the program is  nogc), if the latter then 
use -betterC

IMO, if the interface to your memory allocators is stable then 
just link with them and write the whole thing in D (Interfacing 
with C is a solved problem but C is just awful compared to the 
features you get for free in D)
