Yeah but why has this not happend yet? I have talked some with Ulf
Wiger now and understand why they both exist but not why
timer:send_after has not been deprecated yet. Currently I see no
reason to use timer:send_after. What are your opinions on this matter?
Currently it seems to cause more confusion than useage.
