That reminds me that some time back I tried to get a grip on hash slices. In similar use to your example: my @intersection = grep {defined} @{{map {$_=>$_} @a}}{@b}Though in everyday life I prefer your method, since I tend to get headache from thinking about that slices and also definitely got the syntax and/or semantics wrong the first time always.
