If there's a chance that the script in question will NOT have to call on
this module, you can use the
use autouse 'Date::Calc';
pragma.
I sometimes do this with Carp, for instances where I don't expect carp to
get called very often, in those instances it won't load unless it's needed.
use autouse 'Carp' => qw(carp croak);
Otherwise I generally place all module usage at the top so they are easy to
find for future maintainers.
