Hello,

I'm rather new to clojure and still fighting with the
basics. Just new I wondering why (type (doall x)) is still
clojure.lang.LazySeq? Probably easy but I get no clue, could
anyone help?

user> (def x (range 0 (* 2.0 Math/PI) 0.1))
#'user/x
user> (ns user
  (:require [clojure.contrib.generic.math-functions :as gmath]))
nil
user> (gmath/sin (doall x))
; Evaluation aborted.
No method in multimethod 'sin' for dispatch value: class clojure.lang.LazySeq


user> (type x)
clojure.lang.LazySeq
user> (type (doall x))
clojure.lang.LazySeq


Thanks
Volker
