A workaround:

import std.exception;

struct A
{
     int x;

     this(void* none)
     {
         if (none !is null)
         {
             enforce(0, "Tried to pass a parameter to A's constructor");
         }

         writeln("in constructor");
         // construction from here..
         x = 5;
     }
}

void main()
{
     auto a = A(null);
}

I think that would be safe, and closest to a "default" constructor.

A static opCall would be better. See my answer to the original post.
