I am a C++ game developer and I want to give it a try.
It seems "this" in Dlang is a reference instead of pointer.
How can I pass it as void *?
void foo(void *);
class Pizza {
public:
this() {
Pizza newone = this;
// works but newone is actually not this pizza.
foo(

Even if it were an lvalue, that would be the address of a
local. You should basically NEVER do that with D classes.
Just `cast(void*) this`

unlike c++
The local variable does have its own address. Do not take its
address - avoid &this or &obje
DCD and DMD says that the symbol is undefined!
However, I look into derelichtGLFW3. It has this symbol defined!
It looks like a bug for me!
I came from C++ looking forward to D. Some languages require
programmers to use GC all the time. However, A lot of time we
don't really need GC especially when the time of destruction is
deterministic in compile time.
I found that struct in D is allocate on stack by default. And we
can use sc

I am creating Vector3 structure. I use struct to avoid GC.
However, struct will be copied when passed as parameter to

This is very frequently the correct answer to these questions!
Never assume ref is faster if speed matters - it may not be.
However s
