If you want to see how to use emplace, I'd advise looking at 
std.typecons.RefCounted's implementation:

https://github.com/D-Programming-Language/phobos/blob/master/std/typecons.d#L3505

emplace calls the constructor for you, so I don't know why you'd be trying to 
call it. But you can look at emplace's implementation if you want to see how 
to call __ctor.

For structs:
https://github.com/D-Programming-Language/phobos/blob/master/std/conv.d#L3976

For classes:
https://github.com/D-Programming-Language/phobos/blob/master/std/conv.d#L4716

I don't think that it'll work if the constructor is private though, so maybe 
that's your problem.
