Is this a correct program to explicit call destroy & free ?

void main(){
int[] i=new int[10000];

Yes, first destroy() then free()...
```d
import std.stdio;
import object: doDestroy = destroy;
import core.memory : MEM = GC;
void disposeOf(T)(T obj)
{
auto mem = cast(void*) obj;
scope (exit) MEM.free(mem);
doDestroy(obj);
}
void main()
{
int[] i = new int[1024];
i[$-1] = 41;
doDestroy(i);
MEM.free(i.ptr);
// You don't need to addrOf(cast(void*)i)
//i.length = 1024;
//assert(i[$-1] == 0);
//i[$-1].writeln(" am there?");
if (i !is null)
{
"still alive!".writeln;
disposeOf(i);
}
"bye...".writeln;
}
```
