That's not at all what I said. You don't have to care about 
*when* memory is deallocated, meaning you don't have to manage 
it yourself.

In any case, I disagree that caring about when memory gets 
deallocted means you shouldn't be using GC. (or did I get that 
one wrong too??)

You can have the best of both worlds, surely (and easily).

This (example from first post):

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

    import object: destroy;
    destroy(i);
    import core.memory: GC;
    GC.free(GC.addrOf(cast(void *)(i.ptr)));
}

could (in theory) be replaced with this:

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

    // inscope means 2 things:
    // (1) i cannot be referenced anywhere except within this 
scope.
    // (2) i *will* be GC'd when this scope ends

}
