If we will look at destruction & allocation:
---
import std.stdio;
class C {
int n;
this(int n) { writefln(" this(%s) at %s", this.n = n, cast(void*)this); }
~this() { writefln("~this(%s) at %s", n, cast(void*)this); }
}
void main() {
int i;
writefln("Stack is at %s", &i);
writefln("Heap is at %s", (new void[1]).ptr);
{
C cHeap = new C(0); // will be destroyed on scope exit
scope C c0 = cHeap;
// C(1)-C(4) will be allocated in heap
// C(1), C(2), and C(4) will be destroyed on scope exit
// C(3) will be destroyed on garbage collection
scope C c1 = cast(C)cast(void*)new C(1);
scope C c2 = true ? new C(2) : null;
scope C c3 = (new C(3), new C(4));
}
writefln("after scope");
}
---
As a result even if `C` is a `scope class` the program will compile without
`cHeap` and `c0`, but every `C` instance will be allocated in heap and C(3)
will be destroyed on garbage collection.
