So a namespace prefix is an essential property that is not
part of the symbol's identity. Sounds like we need the
return of the p-list.

(Currently Chez has p-lists, though they are not mutable with
general list procedures; Chicken can be configured to have them
at build time. AFAIK no other Scheme provides them.)
