I would recomend the use of 'my' and 'use strict' in anything bigger
than a throwaway script. And -w for testing too. These will alert
you to many programming errors that would otherwise slip by.
The big advantage for me in using 'my' is Perl yells at me when I do
something dumb, which is a lot. :-)

This I am not sure of. I can't think of any reason, but am not
too familiar on the internals so don't take my word for it.
