I understand now. Given a large list, you'd like to assign chunks of the list to an array, easily, while looping. In other words, you're looking for a way to abbreviate this:
my $chunk_size=10_000; my @big='aaaa'..'mnop'; for ^...@big :by $chunk_size { my @chu...@big[$_..($_+$chunk_size,@big.end).min] ... # Do stuff with @chunk } I'm a perl6 novice so there probably is a more elegant way to write the above already. >From your original email, I like this idea- for 'aaaa'..'mnop' -> *...@chunk[10_000] { ... } # @chunk is 10000 elems or less though I think the syntax has to change a bit. I used the "*@" sigil because "chunk" is slurpy, but only up to 10,000 items. Wrong on a couple levels? By the way, you shouldn't predeclare "@chunk" as you did in the original example- my @a = <1 2 3 4>; my @b[2]; for @a ->@b {;} the @b in the pointy block is a new declaration that shadows the earlier "my @b[2]" declaration.
