Clojurescript NS question

In: https://github.com/clojure/clojurescript/wiki/Differences-from-Clojure It is written than: "You must use the :as form of :require " Does this basically mean there is no natural way to write a set of functions and import them globally (with no namespace prefix)? For example I would like

There's also nailgun: it keeps a JVM running in the background that Java programs can connect to, eliminating JVM startup time completely. It's totally insecure on multi-user machines and hasn't been updated in a while, but it may be sufficient to ease the pain on developer machines. -- You re
