Right, I was vague on the details. How about this?
In Common Lisp, it may be the case that one particular symbol can be
found (e.g. by FIND-SYMBOL) in multiple Lisp packages. But in Emacs
Lisp, a symbol can only be found (e.g. by intern-soft) in one single
obarray. This made me hesitate to use obarrays to implement packages.
However, it can be made to work, and may actually be the best solution.
