This doesn't seem to be possible, however as .filter only takes
unary predicates. I tried:

With normal 'Args', x is not increased because x is copied

Same as above. The general pattern is:
C_Type[] name = new C_Type[](requested_size);
// pass as `name.ptr`. This becomes a C_Type*
Thanks, Adam. Perhaps something like this ought to make its way
into the "D for C Programmers"

If I write 'ref Args' in opDispatch's argument, it fails
because
I'm using opDispatch for wrapping a function like below.
```
import std.stdio;
void func(ref int x, int y) {
x++;
}
struct B {
// wraps 'func'. I want to implement this function.
template opDispatch(string fn) {
void opDispatch(Args...)(Args args) {

isn't unique_ptr typically for heap allocation?
