=> (ns foo (:refer-clojure :exclude [reset!] :as c))
nil
=> (def bar (atom []))
#'foo/bar
=> (reset! bar [42])
#<CompilerException java.lang.Exception: Unable to resolve symbol:
reset! in this context (NO_SOURCE_FILE:1)>
=> (c/reset! bar [42])
#<CompilerException java.lang.Exception: No such namespace: c
(NO_SOURCE_FILE:1)>
=> (clojure.core/reset! bar [42])
[42]
Contrast with:
=> (ns bar (:use [clojure.set :exclude [difference] :as s]))
nil
=> (def baz #{1 2 3})
#'bar/baz
=> (difference baz #{1 4 5})
#<CompilerException java.lang.Exception: Unable to resolve symbol:
difference in this context (NO_SOURCE_FILE:1)>
=> (s/difference baz #{1 4 5})
#{2 3}
IMO, either :as in :refer-clojure should work or it should throw this:
#<CompilerException java.lang.Exception: Unsupported option(s)
supplied: :as (NO_SOURCE_FILE:1)>
Preferably the former.

Master: Your father's Lisp REPL. This is the language of a true
hacker. Not as clumsy or random as C++; a language for a more
civilized age.
