I think we should all recuse ourselves from this discussion, since we just 
keep iterating our same old positions: 
 
Yongwei believes that this is a defect in the standard and that gcc should 
not follow the standard in this respect. 
 
Gaby and I believe that gcc should follow the standard, and probably both 
believe that the standard does not have a defect in this respect. We believe 
that changing the standard would require a massive change in the language, 
since it would either a) require the introduction of concepts (so that 
std::distance can only be called with arguments that match the concept 
of an iterator; same for all other similar functions), or b) abandoning  
argument dependent (Koenig) name lookup. Neither sounds like an appealing 
idea. We believe that users can work around this perceived problem by 
simply calling  
  ::distance (arg1, arg2) 
to get to their own implementation, not the one in std:: 
 
Since we can't seem to find an agreement, let's just leave it at that.
