Description

Syntax quote returns clojure.lang.Cons instead of IPersistenList.
But simple quote always returns list.

(list? '(1))     => true
(list? '(1 2 3)) => true
(list? `(1))     => true
(list? `(1 2 3)) => false

It is unusual in Clojure to expect/rely on concrete list? checks, particularly given the prevalence of seq?

If the behavior documented here is causing problems, please discuss use case on mailing list, and then we can open a ticket.
