It may be a bug somewhere in a Compiler. I've lost track at
https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Compiler.java#L6624
after debugging this:
user> (def x `(quote ~(list 1 (clojure.lang.PersistentTreeMap/create (seq
[1 2 3 4])))))
#'user/x
user> x
(quote (1 #sorted-map (1 2 3 4)))
user> (.eval (clojure.lang.Compiler/analyze
clojure.lang.Compiler$C/EXPRESSION x))
(1 #sorted-map (1 2 3 4))
user> (eval x)
(1 {1 2, 3 4})
