Just to clarify, you want to conj a vector to itself? i.e. [1 2 3 4] --> [1 2 3 4 [1 2 3 4]] I'm curious what the application of this is.
Regarding the overhead of conj-ing to a vector: Clojure's data structures make use of structural sharing so conjoining an element to the end of a vector won't require any copying of entire vectors. It's a cheap, constant(ish) time operation. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
