I disagree. Emacs isn't CommonLisp, never has been CommonLisp and
very likely, never will be CommonLisp.

But at the expense of muddying the waters for people who are not from
that world.

In Emacs world, we use "package" to mean something different from what
CL "package" means. So right at the start that effort is doomed without
a major change to Emacs 24.

I am trying to make a namespace system that would be backwards
compatible with Emacs and yet encourage future good behaviour.

CommonLisp terminology or compatibility is not a major aim of mine.
