For those who haven't been following the design of the Perl 6 language (aka probably 95+% of the people reading this group ;) there's some very interesting feature in the Perl 6 language which basically make set operations first class operators, so you can do this:
if $x == any(@list) {
...
}
Or ...
if $x < all(@list) {
...
}
and then there's hyperoperators, which allow you to specify any operator as applying to each member of an array in turn:
my @new_list = @list ^* 2;
or:
my @new = @old ^* (2, 4, 6); # multiple each of @old by 2, 4, 6 in turn
Since it should be easy to create an @array looking variable that is restricted to unique members, this makes for some very interesting possibilities in terms of set operations, I think.
This is, of course, totally off the current topic ;)
