One thing that's worth mentioning is that while this:
if($foo == 7) { print "foo is 7\n"; } else { print "foo is not 7\n"; }
is acceptable, this:
unless($foo != 7) { print "foo is 7\n"; } else { print "foo is not 7\n"; }
is not. Sure, perl will accept it (I consider this to be a bug in perl), and it'll run, but anyone writing it should be beaten savagely. It's VERY hard to read.
