[erlang-questions] function with no parameter?

[David Mercer]

You should prefix the function call with the module.  E.g., “Module:hej().”

-export([hej/0,fib/1,fibx/1,fac/1, fac2/1, sq/1,cube/1,power/2,
powerc/2,nCk/2]).

hej() -> 12.

this compiles but it doesnt work when calling in the shell.

36> hej(). 
** exception error: undefined function shell_default:hej/0

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?
