Make our own version of DBRef that is exactly like the original but has one extra constructor and
implements clojure.lang.IDeref so it is possible to @dereference such refs.
This is only one small step in a proper, Clojuric, easy to use DBRef support. We may tack more Monger-specific
extensions to our DBRef implementation later.
As sang by Jetallica:
Do unto others as they have done unto you
but what in the hell is this world coming to?
Blow the universe into nothingness
nuclear warfare shall lay us to rest
Fight Java with Java
ending is near
fight Java with Java
bursting with fear
