[erlang-questions] Optional callbacks

Started trying to play with those, and not managing to get a warning 
from Dialyzer.

When I change the body of the function to 'ok', I do get a warning for a 
normal callback, and I get nothing for an optional callback.

Is that normal?

The behaviour_info function does return the callback as optional.
