If you use the package name then you don't need to use our():

True.
But if you don't use 'our' you would always have to use its
fully-qualified name.
$main::please_die = 0;
$SIG{TERM} = sub { $main::please_die = 1; };
instead of:
our $please_die = 0;
$SIG{TERM} = sub { $please_die = 1; };
Of course, you could shorten your keystrokes by using '$::please_die'
