in reply to Combining arrays with grep/unless?

List::Compare was built for working with two, three or more arrays at once.

use List::Compare; my @Llist = ('A','B','C','D','E'); my @Rlist = ( 'D','E','F','G','H','I','J'); my $lc = List::Compare->new(\@Llist, \@Rlist); # If I read your post correctly, # this is what you want. my @LorRonly = $lc->get_symmetric_difference; print join ", ", @LorRonly; # Also does... my @intersection = $lc->get_intersection; my @union = $lc->get_union; # And much, much more.

A, B, C, F, G, H, I, J

[Corion]: ... coworkers have. But I guess I've gone more mellow since I get to relax more, and such stuff doesn't make me as angry as it used to.
[Corion]: $boss will still get to listen to my interpretation :-D
