Better solution:

my %seen;
my @uniqWebCustomers = grep !$seen{$_}++, @webCustomers;

Better yet:

use List::Util qw( uniq );

my @uniqWebCustomers = uniq @webCustomers;

I agree with the "Better yet," but in situations where I do something like option 1, I like to wrap it in a do block to maintain tight scoping: `my @uniqWebCustomers = do{ my %seen; grep !$seen{$_}++, @webCustomers; };` [download] #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply] [d/l]

If you're going to add a block, make it a sub. `sub uniq { my %seen; grep !$seen{$_}++, @_ } my @uniqWebCustomers = uniq @webCustomers;` [download]	[reply] [d/l]
