timing sleep

[Parth Malwankar]

Hello,

Here is something I tried.

user=> (. Thread sleep 1000)
nil
user=> (time (. Thread sleep 1000))
java.lang.ClassFormatError: Field "ret__834" in class user/eval__2163
has illegal signature "V"

user=> (time (* 10 10))
"Elapsed time: 0.077316 msecs"
100
user=>

Is it not possible to time (. Thread sleep 1000)? What I am doing
wrong?

Thanks.

Wrapping it in another function seems to work though:

user=> (defn big-computation [x] (. Thread sleep 1000) (* 10 x))
#'user/big-computation
user=> (time (big-computation 1))
"Elapsed time: 1012.272771 msecs"
10
user=>

Fixed - thanks for the report.
