A combination of the two might prove useful. Allow bearophile's suggestion 
but only with some variant of module(system) at the top. Files using this 
would still be easy to find but it would also (if the internal tag is easy 
to grep for) limit the lines that need to be reviewed.

Keeping the current form as well would be good.
