they can add up quick:
% perlbloat 'use POSIX ()'
use POSIX () added 316k
% perlbloat 'use POSIX'
use POSIX added 696k
that's 380k worth of aliases. now let's say 6 different registry scripts
'use POSIX;' for strftime or whatever, 6 * 380k = 2.3Mb
they could save 2.3Mb with 'use POSIX ();' and fully qualifying POSIX::
function calls.
so a few 'use vars ()' here and there doesn't eat that much, your call.
