but this(const this) is supported and means to be a constructor

Maxim, please review this thread: 
http://forum.dlang.org/post/lrnxsvtwqwqtydggj...@forum.dlang.org

In this example the 'this(const this)' is not called, just as 
pointed out in the previous thread. That is, things have not 
changed.
So, in following, "Hi" is not printed. Have you had any luck with 
'this(const this)'?

Thanks
Dan

import std.stdio;

struct X {
  char[] c;
  this(char[] c_) { c = c_.dup; }
  this(const this) {
    writeln("Hi");
  }
}

void main() {
  auto const x = X(['a']);
  const(X) x2 = x;
  writeln("Done");
}
