Hello! Currently, 'pop' throws an exception if the collection is empty: clojure.core/pop ([coll]) For a list or queue, returns a new list/queue without the first item, for a vector, returns a new vector without the last item. If the collection is empty, throws an exception. Note - not the same as next/butlast.
user=> (pop ()) java.lang.IllegalStateException: Can't pop empty list (NO_SOURCE_FILE: 0) user=> (pop []) java.lang.IllegalStateException: Can't pop empty vector (NO_SOURCE_FILE:0) Should (pop nil) also throw an exception or is returning 'nil' ok?? user=> (pop nil) nil Thank you, Frantisek --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
