If this is pure Perl then it doesn't make any difference.
if (
($_
eq $bad_guys_ip) )
{more_stuff_here };
is fine (although the second pair of parentheses won't make any
difference either) as long as you also have a
sub more_stuff_here;
somewhere!
Can you give us a
bit more context, and say what error you're getting?
Cheers,
Rob
