Re: [boost] Any Interest? Name/Value pair TokenizerFunction

if it always find an even number, wouldn't   std::pair<std::string, 
std::string> be a better thing to produce?
your outputs would then be:
{
cout << '[' << iter->first << "]/[" << iter->second << ']' << endl;
++iter;
}
no more having to deal with odd even increments.
