I think that dash addresses most of these. The namespacing is minimal
(with a -) and it's not particularly large, although in these days of
fast machines, I am not sure that "large" is such a problem as it might
have been in the past. I am often surprised by how much emacs can do
nowadays which would have been slow before.
