How can I create a map that has the same content as another rmap, except 
for a given key which has a new associated value ? I'm looking for 
something like replace_key<Key>(Sequence, Value) in the doc but I cannot 
find it. I think I can build it with push_back(erase_key<Key>(seq), 
make_pair<Key>(newval)) but if it already exists...

Thanks,
