Anybody want to try their hand at a fast and efficient map:merge() function?

map:merge( map_one, map_two ) -- merge map_two into map_one (?) 

or something like that.

This needs to be in std/map.e.

Returns:
If dest_map was not provided, an exact duplicate of source_map otherwise dest_map, which does not have to be empty, is returned with the new values copied from source_map, according to the put_operation value.
