sleep-for does not work as expected - or perhaps my expection is incorrect

[C K Kashyap]

Hi,

(defun somefun ()
  (insert "Hello ")
  (sleep-for 1)
(insert "world\n"))

 

When I invoke "somefun" by doign -  M-: (somefun) <return>

 

I see that "Hello world" gets printed after 1 second instead of printing Hello and then printing world after one second.

 

What can I do to get the script to write out "hello" first and then wait for a second and then write out world?

 

Regards,

Kashyap
