While examining the Clojure source I came across this line in the EmptyList class:
public boolean equals(Object o) { return (o instanceof Sequential || o instanceof List) && RT.seq(o) == null; } What's up with the RT.seq(o) == null? Why don't we do this instead: public boolean equals(Object o) { return (o instanceof Sequential || o instanceof List) && o instanceof Seqable && ((Seqable)o).seq(o) == null; } I've seen RT used in other places as well, I guess I don't understand why it's used here, or what it is at all....
