Oops! Not AFAICS. Consider its equivalent for:

for(typename Container::const_iterator j = c.begin();
    j != c.end(); ++j)
  newPrint(*j, out);

This means that _1 is meant to recieve
*Container::const_iterator which is exactly what I
pass to for_each:

for_each(c.begin(), c.end(), bind(newPrint, _2, out));

Hmmm... I guess I know enough about those trivial
situations. And, I need it as it is. Furthermore, the
for loop works, which means that there shouldn't be
ant problem any way else... :(
