Not in the sense that you can enumerate a reified namespace in Clojure
- ns-publics et al. Those things are 'in' the namespace, and that
notion of namespace is a collection.
In the sense that you can use part of a name to partition the set of
all names, yes, but that is a weaker notion of namespace, and the same
sense as - all names beginning with 'P' is a namespace.
Clojure names have distinct namespace components so they can be used
to designate/find things in namespaces.
