Yes, the semantics of a sequence force it to be immutable :
Seqs differ from iterators in that they are persistent and
immutable ( http://clojure.org/sequences )
So there's simply no need to have a copy function for sequences (or
for any other clojure data structure).

Hello,
I wanted to know if I was alone thinking that 'mapcat' should better
have been named 'catmap' ?
When reading code, this looks more natural because it resembles the
functional composition of the 2 functions : (cat (map ...))
I know this is an inheritence from older lisp dialects, but
