Clojure doesn’t provide it as a part of the `ns` or `import` forms, but
the underlying `Namespace` objects support it just fine, and then almost
everything works as you’d expect w/ the arbitrary alias:
user> (.importClass *ns* 'Q java.util.concurrent.LinkedBlockingQueue)
java.util.concurrent.LinkedBlockingQueue
user> Q
java.util.concurrent.LinkedBlockingQueue
user> (Q.)
#<LinkedBlockingQueue []>
user> (fn [q x] (.offer q x))
Reflection warning, /tmp/form-init7252328014986537096.clj:1:11 - call to
offer can't be resolved.
#<user$eval1302$fn__1303 user$eval1302$fn__1303@ece88d2>
user> (fn [q x] (.offer ^Q q x))
#<user$eval1308$fn__1309 user$eval1308$fn__1309@251c4123>
