Re: Defining a cast on a templated class

I'm creating a sort-of "wrapper" class which (partly) acts like a
variable. Something like:
template<class t>
class cell{
  t curval;
public:
  /*public for debugging only - will be private in final version*/
  inline cell<t>& set_value(t v){ curval = v; return *this;}
  inline t get_value(){ return curval;}
  /*actual public interface*/
  /*assign to this value*/
  inline cell<t>& operator=(t v){ return set_value(v);}};

...
int
main(void){
  cell<int> v;
  v = 0;
  cout << "v = " << ((int)v);
  return 0;

}

However I can't figure out how to make the compiler do v.get_value()
when v is used in an int() context. Since this is templated, the only
conversion I want to support is something like cell<type> -> type.
Attempts to convert to unrelated types should signal an error.

I can't figure out the correct syntax to do this, unfortunately
(should probably look for better manuals, sigh).
