I'm suffering from idiom-dazzle! This works:

use strict;
my @toBeMoved = qw(133 22 103 133 133 22 1 999);
my %h;
$h{$_} = 1 for @toBeMoved;
@toBeMoved = sort {$a <=> $b} keys %h;
print "@toBeMoved\n";

But what's up with the increment and equality test inside of the grep? I'm reading this as each grep pass will set the value of the current hash element to 1 by the increment operator, but what's going on w/ the equality test? Would a kindly monk please break this grep block down for me?
