Hi All,
  I've come across a code technique I couldn't find documented anywhere. It's a clever way of deleting multiple hash keys:- 
my %hash = ( a => 1, b => 2, c => 3 );
delete @hash{qw/a b/};

I don't fully understand why the @ is used. I guess because the qw is returning multiple values.
I was hoping someone could tell me what this is called, point me onto the right docs, or maybe even show similar clever hash techniques.
