Is there a macro like 'time' in Clojure?
Hello, I’m a beginner of Elixir.
I wonder if there is a macro like ‘time’ in Clojure.
It can tell the time our function took.
user> (time (Thread/sleep 100))
"Elapsed time: 100.284772 msecs"
nil
Maybe it’s convenient when optimizing our functions.

To answer the question, there’s a simple function in erlang to accomplish this:
{time, value} = :timer.tc(fn -> do_some_stuff() end)
It returns time in microseconds:
