Thats a great feature as well! It is very good not to clutter the code with
magic constants, but to be able to name them in a sane way.
Thank you all again,

Not sure if this is what you want, but Clojure 1.3 introduced ^:const.
This lets you store a primitive constant value:
(def ^:const hash -3750763034362895579)
Then you ca
David and Stu to the rescue. Of course that's the way to do it.
Thank you both,

You can't store primitives in vars. But you can cast their contents to
primitives with (long ...) (int ...) etc

None. Both are syntax sugar for (. Long MAX_VALUE)

unchecked-multiply only does unchecked a
I try to do multiplication where overflowing is expected and the result
should be handled "modulo" ie the multiplication results in a truncated
long.

1 ;;is ok and expected
also
classificator.fnvhash> (unchecked-multiply Long/MAX_VALUE
