But how can I bind Wrapper\<void> in D? Specifically, how do I
even express that template specialization in D syntax?
Did you mean any of these?
1. Parameter specialization:
```d
extern(C++, class):
class Wrapper(T) {...}
class Wrapper(T : void) {...}
```
2. Template constraints:
```d
extern(C++, class):
class Wrapper(T) if(!is(T == void)) {...}
class Wrapper(T) if(is(T == void)) {...}
```
3. `static if`:
```d
extern(C++, class)
class Wrapper(T) {
static if (!is(T == void))
private T t;
private bool valid;
public final isValid();
}
```
Thanks! This got me unstuck. I've picked the first solution. It
mirrors the C++ code nicely.
The embarrassing part is that I should have known the other two
options, but my head got completely stuck trying to convert C++
to D too literally.
