[erlang-questions] function with no parameter?

[Doug Edmunds]

I doubt any of them work unless you prefix the function
with the name of the module (unless you are shadowing
a BIF, in which case you are really calling the BIF and
not yours.

the tipoff is 'undefined function'

try this:
whatever_the_module_name_is:hej().

which will work, as long as the module is in the
search path.
