surprised that this is valid...

Hi all,

I've per chance noticed that this code compiles without warnings:

struct x
{
  x(): y_( y_ ){}

  int y_;
};

I've used gcc 4.1.0, comeau online and all compilers available at
dinkumware online.

Are there cases where similar code (a member initialising itself with
itself) would make sense? I was surprised when I discovered this.

Regards,

Werner
