I did say he would have to use a naming convention and
that in turn implies the use of glob to filter the names returned.
But I agree it has risks but then, so does relying on
always editing init.py

I just prefer to avoid introducing hard to remember
maintenance tasks when I can do it automatically,
but of course you need to remember the naming convention.
But hopefully a quick 'ls' will do that for you...
