in thread Hash versus chain of elsifs

my %junksites = ( "bollyinside.com", "www.bollyinside.com", ... "worldtrademarkreview.com", "www.worldtrademarkreview.com", );

Note that hash needs key and value pairs, so you're storing only the site names without www as keys; the www. prefixed ones are stored as values. Probably not what you want.

The fast way how to initialize the keys is

my %junksites; @junksites{qw{ bollyinside.com www.bollyinside.com ... worldtrademarkreview.com www.worldtrademarkreview.com }} = ();

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
