Mostly efficiency. A Seq generally gives you access to `first` and `rest` in constant time. Vectors, to take one example, cannot give you `rest` efficiently, but a Seq backed by the vector can.
Clojure lists are implemented as singly-linked lists, which do have first/rest pointers, so they implement ISeq directly. -S -- You received this message because you are subscribed to the Google Groups "Clojure" group.
