While discussing RT #129321 TimToady found another problem with duckmap, see http://irclog.perlgeek.de/perl6/2016-09-26#i_13285724 The problem can be shown with a couple of examples, one with duckmap where structure is lost dogbert@dogbert-VirtualBox ~/repos/rakudo $ ./perl6 -e 'my @a = [1, [2,3],4]; dd duckmap(-> Int $x { $x ~~ Int ?? $x !! Any }, @a)' (1, (2, 3), 4) According to TimToady the result should have been [1, [2, 3], 4] deepmap, on other hand, does retain structure as can be shown with dogbert@dogbert-VirtualBox ~/repos/rakudo $ ./perl6 -e 'my @a = [1,[2,3],4]; say @a.deepmap({ $_ + 1 })' [2 [3 4] 5] /dogbert17
