You can always simulate your own n-ary map using gather:

gather {
  for @loop Y @pos -> $arr, $i {
    take $a[ $i ];
  }
}

Although allowing map to take multiple items from the list at once would be nicer, and it's something I've wanted rather often.

Sure, works in current Pugs! :) `@result = map { $^a + $^b } 1,2,3,4; # 3,7 @result = map -> $a, $b { $a + $^b } 1,2,3,4; # 3,7 # And: $result = reduce { $^a + $^b * $^c } 1,2,3,4,5; # same as $result = (1 + 2 * 3) + 4 * 5; # i.e. # 27` [download] --Ingo	[reply] [d/l]
