We blitzed a discussion on #perl 3 minutes ago, reaching the conclusion that negated subscripts are cool.
So i was thinking: subscripts are objects. They are sets, really. You can perform set operations on them: [!-2] is the subscript for everything but the second to last element. By using a context enforcer (subscript  ?, maybe since lists are lazyy they can just be subscripts when used that way?) you can get a subscript object, which you can then use in a subscript, and it flattens out. The set math is done by special casing junctions, perhaps? my @array; @array[$subscript]; @array[$other]; @array[$subscript | $other]; # union @array[$subscript & $other]; # intersection @array[!-1]; # -1 but false? this means that it's masking my $not_1 = [!-1]; @array[$subscript & $not_1]; # subscript without -1 @array[$subscript | $not_1]; # subscript with -1, since it's a union # with the complement of just -1 I've found myself replicating sets like these for accessing data many a time in perl 5. Maybe if refined this can be useful? -- () Yuval Kogman <[EMAIL PROTECTED]> 0xEBD27418 perl hacker & /\ kung foo master: /me wields bonsai kittens: neeyah!!!!!!!!!!!!!!!!
