but I was unforgivable lazy and post an Ill-formed program (should have
tested first!)

Could you tyr again with this corrected version?

template<class T>
struct X
{
  X();
  X ( X const& ) ;
  template<class U> X ( X<U> const& ) ;
} ;

template<class T>
struct Y
{
  Y();
  Y ( Y const& ) ;
  explicit template<class U> Y ( Y<U> const& ) ;
} ;

template<class T> void eat ( X<T> ) ;
template<class T> void eat ( Y<T> ) ;

int main()
{
  X<int> x1 ;
  X<int> x2 = x1;
  eat(x1);

  Y<int> y1 ;
  Y<int> y2 = y1;
  eat(y1);
}

Thanks,
