The following script illustrates a program with sets a member
of a class object which is declared const using a non-const member
function.  It is my understanding that this should be flagged
during compilation as an error.

robbie(1)->cat b.cc

class foo{
  int x;
  public:
  void set(int i) { x = i; }
};

main(void)
{
  const foo i;

  i.set(24);
}

This is fixed in a later beta release...
