Can't be done using the standard Java library. You'll have to write

Hi everyone,
I'm just wondering where the equivalent of the ">>>" operator is for
Clojure. I need it to do a divide-by-power-of-2 on unsigned bytes.

Speaking of "walking/filtering code," what about walking _actual_ code?
The only thing off the top of my mind would be an example of, say, a "Hello
World" function, but with the code represented as a JTree. Say, in the
function (pr (.toLowerCase "Hello World")), you'd see .toLowerCase as a
node.

Hi,
I noticed that one part of my code was being obscenely slow, so I set
*warn-on-reflection* to true.
(let [b (byte 30)]
(> b 30))
gives Reflection warning, NO_SOURCE_PATH:498 - call to gt can't be
resolved.
But:
(let [b (int 30)]
(> b 30))
Is there a reason for having a byte-overloaded
