Same thing in D without the semicolon. :)

Like in Java and C#, class variables are object references in
D. So, the following is sufficient:
SpriteRenderer Renderer; // Although, I would name it
'renderer'
However, unlike C++, that variable is thread-local, meaning
that if you have more than one thread, each will have their own
variable. If you really need it, in multithreaded code you may
want to define it shared:
shared(SpriteRenderer) renderer;
But then you will have to deal with thread synchronization.

There is something here:

Ok. I was trying something more D like, by doing:
SpriteRenderer Renderer = new SpriteRenderer();
I believe this won't work because I'm trying to allocate memory
outside of any class, structure, or function?
May I ask sort of an aside question. In large projects with 1000s
of line of code and many many modules, classes, structs, and
functions; is it probably true that most of the time the vast
majority of variables are going to be inside one of above
constructs?
And is there a name for the variables that fall outside of the
above constructs?
I see so many tiny code snippets in books and docs, that when I
do look at large dub/github projects, I'm not sure how to
organize the "stuff" that slops over the edges.
