Not really, but then again, if you are not placing the class into the

No, I *am* placing it on the heap.
You hadn't made that clear.
In your first post, I was assuming your ptr came from some non-GC
allocated space, which is why you wanted the ability to intercept it.
I'm just asking if I can call the constructor manually, because
(like I wrote in my first post...) sometimes the C code you're
interoperating with takes control away from you, and just calls a
callback on your behalf when constructing the object.
I wasn't sure, but I just tried it out:
import std.stdio;
extern(C) void *_d_newclass(TypeInfo t); // this is defined in
rt/lifetime.d I cheated and used this, because I didn't want to have to
type everything that was in it :)
class C
{
int x;
this(int x){this.x = x;}
}
void main()
{
C c = cast(C)_d_newclass(typeid(C));
c.__ctor(1);
writeln(c.x); // outputs 1
}
Seems to work
