Oh, and while we are at it, it would be great to allow multiple
behaviours with shared callback functions to compile without warnings.
My single file supervisor/gen_server/gen_event logger module had to
comment out two of the -behaviour lines. Almost totally while using
good coding standard too.
Either that or disallow multiple behaviours in the same file in general.
