hej() -> 12.<br>
<br>
this compiles but it doesnt work when calling in the shell.<br>
<br>
36> hej(). <br>
** exception error: undefined function shell_default:hej/0<br>
<br>
does this have anything to do with functions should be pure in erlang thus
calling a fucntion with no parameter isnt allowed? but then why is creating
them allowed?</p>
