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(_at_list) {

     ...
  }

Or ...

  if $x < all(_at_list) {

     ...
  }

and then there's hyperoperators, which allow you to specify any operator as applying to each member of an array in turn:

  my _at_new_list = @list ^* 2;

or:

  my _at_new = @old ^* (2, 4, 6); # multiple each of @old by 2, 4, 6 in turn

Since it should be easy to create an _at_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 ;)
