🚀 go-pugleaf

Now that I've got g++ working here (thanks those who responded to my
earlier plea for help), I've got another problem...
The following code fragment (from InterViews):
  class Resource {
  public:
      Resource () { refcount = 1; }
      ~Resource () { if (--refcount > 0) { this = 0; } }
  
      void Reference () { ++refcount; }
      int LastRef () { return refcount == 1; }
  private:
      unsigned refcount;
  };

Generates the following error message:
  foo.c: In method Resource::~Resource ():
  foo.c:4: assignment of read-only parameter `$this'

As far as I can tell from Stroustrup, this appears to be a perfectly
valid use of THIS in a destructer.  What's going on here?
