Yes. D constructors are not named but the current implementation 
adds a name that is `__ctor`, so add

```d
alias add = __ctor;
```

to you struct.

Note that however this kind of internal details should not be 
used, even if chances that this name changes are low (old 2014 
code that uses it still compiles and have never broke, phobos 
uses it too IIRC).

Otherwise take care to copy construction, that wont work with the 
alias.
