Is this possible in D2?

i.e. I'm wondering if there is a way to do the object
construction yourself, which would allow you to call the object's
"constructor" (initializer) manually, and just return a pointer
to the new object.

Something along the lines of:

class Window
{
static Window opConstruct(void* ptr)
{
// Assume ptr is already correctly sized and filled
Window result = cast(Window)ptr;
result.__ctor();
return return result;
}
}

It seems like overloading new() *almost* does this, but not
quite: It only lets you allocate the memory, not call the
constructor yourself.

This would be useful, because some objects can have external
constructors (notably when interfacing with C/C++, such as when
using CreateWindow() in Windows), and you *cannot* call these
constructors inside the object's "constructor" (initializer) due
to re-entrancy issues.

Don't know if it helps but, have a look the DWT sources:

https://github.com/d-widget-toolkit/org.eclipse.swt.win32.win32.x86/tree/master/src/org/eclipse/swt

should probably be in the internal folder, widgets/Widget or widgets/Shell.
