C has no notion of shared, so it's not the right type. Putting

Better to be explicit about what it is.
Nonsense. Putting `shared` on a shared variable is not "lying".
It doesn't matter if C makes the distinction. D does.
I'm not saying you should use `__gshared` liberally, or for
cases where you are using this only in D. But to say you should
*never* use it is incorrect.
If you're clever enough to identify a valid use case for
`__gshared` and write correct code with it, then you're clever
enough to figure out when not to listen to me.
Everyone else, don't ever use `__gshared` ever.
`__gshared` is about as bad as `-boundscheck=off`. They're both
glaring safety holes. But people want to be propper hackers (TM).
And propper hackers know how to handle these foot-guns, of
course. And then they shoot their feet off.
