My bad, I meant 'fill', not 'assign'. I confused it with the assign 
member of containers.

boost::fill being just like std::fill but taking a range instead of two 
iterators. It's in the accepted update to the range library that doesn't 
seem to be in the trunk yet.

Otherwise, you'd have to write

std::pair<TheMap::iterator, TheMap::iterator> r = m.equal_range(old_key);
std::assign(r.first, r.second, new_key);
