Flattening nothing gives something? Flatten is not consistent with seq: user=> (flatten ()) nil user=> (flatten []) nil user=> (flatten 0) java.lang.IllegalArgumentException: Don't know how to create ISeq from: Integer user=> (flatten nil) (nil) user=> (seq ()) nil user=> (seq []) nil user=> (seq 0) java.lang.IllegalArgumentException: Don't know how to create ISeq from: Integer user=> (seq nil) nil > Not a bug.
