In Clojure, namespaces are different from the host's packages, in
ClojureScript they are the same (insofar as they match the Google
Closure approach).
Why all the attention to :use - I thought everyone agreed using it is
a bad idea?
In any case, ClojureScript is a subset and right now that subset
doesn't include :use. People who want it will have to explain why they
think it's important. Its cost is that namespaces have to be
enumerable, which poses challenges for code (re)loading and modularity
for Clojure. The only benefit I see is that you can avoid a (minimum 2
character) prefix.

In Clojure, there is a clear distinction between using Clojure
namespaces and importing interop packages.
Is it a goal then to blur that line in ClojureScript?
'use' couldn't be used analogously just for ClojureScript names as
it is in Clojure?

:use requires the ability to determine all the names in a namespace,
something we don't generally have in ClojureScript, especially for JS
pseudo-namespaces.
